5 Best Knot Dildos [Video Demonstration]

While they might be unusual, knot dildos are an exciting addition to your sex toy collection! These fantasy toys help you enjoy the often-suppressed animal instinct that makes us humans. After all, we’re all humans. Aren’t we?

After testing dozens of products, we firmly believe Uberrime Ardor is the highest-rated knot dildo. The dragon monster has a musculature and marbled silicone coloration representing top-notch artwork that we rated higher than the other review samples. Our testers also loved how the narrow head is bent about 45˚, making targeting the G-spot and P-spot easy. And with a chunky mid-shaft knot, Ardor is extremely satisfying, with a unique filling sensations blend.

Why You Should Trust Us

Sandra Larson has been in the sex toy industry for about seven years, and no sex expert comes close to her regarding sex toy expertise. Besides reviewing the dildos, she also works with a team of sex experts at My Sex Toy Guide to match our readers with the highest-rated knot dildos for their sexual needs and desires.

Our product test team has tested over 300 sex toys, including the knotted models with a knobby stem for extra stimulation. For this article, Sandra spearheaded a multi-faceted approach that combined in-house testing and comparison with other sex toy users’ experiences to understand the pros and cons of each product.

If you want to see what the knot dildos look like and how to use them, please watch my unboxing and demonstration video below:

How We Picked the Products

When I picked the products for review, I took the team through the absolute deal-breakers customers consider when buying their products. These motivations are designed to ensure the products we recommend match your sexual needs and desires. I instructed each team member to spend time with the dildos and share their scores. Once we finalized everything, I defined test criteria that we could measure on a scale from 0 to 100. These factors included the following:

• Build Quality. As we’ve done throughout the years, we only reviewed products made from hypoallergenic, body-safe materials like silicone, glass, and metal. While we also tested other alternatives like TPE, we don’t recommend the non-porous material because it complicates cleaning and overall maintenance. If you want your sex toys to last, we highly recommend sticking with silicone dildos.
• Design. We reviewed numerous shapes and designs to ensure we offer a wide variety for our readers. Everything from the texture to the knot build was unique for each reviewed dildo. And with most of them designed to mimic fantasy creatures, our readers can expect an exciting blend of sensations. Whether you want to fulfill your alien or canine fantasies, there’s something for everyone.
• Size. The size was another essential consideration when we picked our test samples. For this reason, we reviewed differently-sized models to ensure every user had something to work with.
• Firmness. Most knot dildos have a rough texture to keep up with the ‘brutal’ fictional persona. However, the density varies from one model to another, and the team included different firmness degrees to enhance the user’s comfort.
• Stimulation. Another exciting feature we considered was the sensations. For this reason, we included different stimulation types, including thrusting, squirting, and vibrating models.
• Price. In the full realization that the price depends on the design, material, and size, the review team looked into different products in the price spectrum—everything from the high-end top picks to the bargains for sex toy users on a budget.

When the team returned, we analyzed the reports. We used comparison tables and pie charts to identify similarities between the review samples. During testing, we rated each of the toys based on the criteria listed above starting from 0% (Worst) to 100% (Best). Each score was calculated using different weighted metrics depending on what we deemed most important. Half the total rating comes from Design (25%) and Quality (25%). After that comes Sensation (10%), Special features (10%), and Price (5%).

In addition, the team used reviews and comments from vendor sites to understand the public perception. And from the collaborative effort, we believe these are this year’s best knot dildos!

Everything We Tested

In this chapter, you can see a comparison table with all the products we tested. As you can see, each row has the test criteria our team used during the testing. To make our testing process even more transparent, we also included the raw test data so you can see how the products performed with each test criteria.

1. Uberrime Ardor: Our Overall Test Winner!

Why we love Uberrime Ardor:

Among the knot dildos we tested, Ardor Dragon of Lust by Uberrime stood out the most, thanks to the impressive design that blended fantasy with realism. Unlike other review samples in the article, the piece was more focused on gradual, fulfilling pleasure over harsh textures and extreme intensity, making it cozy enough for most users to enjoy. Its soft silicone finish and subtle knot offered a formidable challenge without being overwhelming. More importantly, our testers found it easy to use, extremely dynamic, and functional.

The design was the primary reason we picked Ardor as our test winner. The brand took everything sex toy users adore about fantasy dildos and put together one of the most functional models. Even with the intimidating demeanor, we loved how the tapered head simplified penetration. In addition, the transition from the graduating build of the head to the knot was seamless. “I expected a more aggressive approach, but Uberrime provided the right amount of fullness that gives you the urge to carry on and see what the knot has in store,” our product test lead Sandra Larson wrote in her test report. “The knot was protruding, but the overall soft texture meant the experience was more fun than it was overwhelming.”

Note: The team also loved the color switch. When exposed to direct light, the dildo changed from dusky blue to an exciting teal and shimmery glitter. The magical touch inspired a unique feeling of sexiness you don’t get with regular dildos,” says Rachel Sommer, our in-house sexologist.

Our only concern with the design was the squishy material on the knot. Although that’s what makes it comfortable, the more experienced users looking for rock-hard sensations and dramatic stretching might not hit the mark with the Ardor. The product is perfect for folks seeking a comfortable fantasy thrill.

As mentioned before, the Ardor is designed for a blend of a smooth feeling of fullness that gradually builds into intense orgasms.  Rough, aggressive pressure won’t work with the dildo, but the overflowing full sensation will certainly move you.

The textured plates and knot gently drags against the vaginal walls as you insert the dildo. In addition, each thrust attracts a measured resistance from the silicone material, creating the foundation for slow, satisfying pressure. “It’s one of those models that aren’t ‘in your face’ type of fun,” says Sandra Larson. “The sensations are more intimate and include slow thrusts and an overriding feeling of fullness.”

The fantasy dildo is among the most versatile picks in the article. Our testers highlighted how it complements your sex life, whether solo or with a partner. The well-measured density makes it flexible and easy to manipulate for maximum enjoyment. In addition, the waterproof model is aquatic fun-ready, and you can enjoy the sensations in the shower or bath.

Uberrime Ardor is made from high-quality silicone. Besides being soft and enjoyable to use, the material holds its shape, and its flexibility means you can explore different positions and angles. The attention to detail was evident from the first glance, and although Jessica and I have had it for three months now, it feels brand new,” says Rachel Sommer. Cleaning is straightforward, and it doesn’t attract dust and lint like other fantasy models in our collection.”

Minor issues we found during testing:

Unfortunately, some users have described Uberrime Ardor as too soft. It might not be your wisest choice if you’re seeking something aggressive and firm for pounding pressure.

The size can be too much for newbies. If you’ve not used fantasy dildos before, don’t let the flexible silicone material fool you; Ardor’s girth and knot take some getting used to.

Why Uberrime Ardor is the best knot dildo:

• Design: Uberrime Ardor was our overall test winner because of the thoughtful blend of fantasy and realism. Other review samples were more aggressive and pressure-motivated, but this piece emphasized gradual intensity and an overriding feeling of fullness. The seamless design and subtle knot offered a formidable challenge without being overwhelming. Everything from the tapered head to the smooth silicone and flexible body provided a dynamic and comfortable experience for people looking to enjoy fantasy dildos with a dash of real-world functionality.
• Versatility: The product’s well-measured density with smooth silicone that was firm enough to maintain its shape made it ideal for different users. In addition, the dynamic piece offered a haven for solo users and couples. And with the waterproof design, you can confidently use it in the shower or bath. The best part was that you could also get the medium version with 6.5″ insertable length and 2.31″ diameter if you want more fullness.
• Build Quality: Our testers highlighted how the attention to detail was evident from the get-go. The product is made from high-quality silicone and the well-thought-out texture plates and knot offered satisfying sensations as they glided over the vaginal wall. Although squishy, the material was firm enough to hold its shape, and even after repeated use, Ardor feels brand new.

2. SquarePegToys Happy Hour: Budget Pick!

Why we love SquarePegToys Happy Hour:

If you’re curious about knot dildos and aren’t sure if they’ll be worth it, the Happy Hour from SquarePegToys is the perfect starting point. For starters, it only costs $34, a massive bargain for the well-designed and easy-to-use piece. More importantly, the chill plug is beginner-friendly, with the perfect blend of softness, comfort, and gradual stretching, allowing newbies to explore the knot experience without being overwhelmed.

Besides the competitive pricing that makes it perfect for newbies and sex toy collectors, the team was surprised at the variety. The Happy Hour is available in eight different sizes, ranging from 5.3″ to 9.6″. With such a variation, you can be sure you’ll find the perfect size for you. In addition, there were two color options to choose from, so you’re not stuck with something that’s not visually appealing to you.

The design was another highlight of the review. Although simplistic, we thought it was clever because of the tapered head (closeup in the image above), which made insertion easy. The knot wasn’t harsh either, but it was a slow swelling that offered a formidable challenge to the user. Our testers highlighted how the sturdy T-base enhanced safety and avoided unwanted travel when using the Happy Hour Plug for anal exploration.

The Happy Hour plug offered a slow and steady feeling of fullness that’s uncommon with fantasy dildos. Unlike the usual violent pounding, this plug starts mild and gradually builds up into a constant sense of fullness. “It felt good, and the knot added a slight pop to the thrusting session, making stroking more thrilling,” says our male tester Shane Davis. “Although a bit gentle, there was no assumption of knot’s effect on the overall experience.”

The solid craftsmanship was evident from the get-go. Everything from the smooth seams to the consistent color, and well-thought-out shape amplified the brand’s efforts to enhance the user experience. “Our Happy Hour has maintained its shape after more than a dozen uses,” says Rachel Sommer. “The silicone material, tapered design, and well-balanced density mean it feels like the first time, every time.”

Using the Happy Hour Plug was straightforward. Even for newbies looking to explore the world of knotted toys, the experience was blissful. “The tapered head made it easy to slip the dildo inside, and the cozy silicone material was easy to manipulate so the knot could slide through,” says Rachel Sommer. “Of course, plenty of lube is a must, but the extended neck, tapering, and cozy finish made the difference.”

Lastly, the versatile dildo serves as a gentle stretching tool for beginners looking to explore knotting toys. In addition, the toy is available in eight different sizes, allowing users to choose the specific dimensions to match their experience and sexual mood. You can even wear the smaller models during foreplay or sex for an amplified feeling of fullness.

Minor issues we found during testing:

Unfortunately, the S2 (smallest size) might feel too underwhelming if this is not your first sex toy experience. We recommend checking the dimensions and comparing them to your other toys before deciding on the ideal size to buy.

Why SquarePegToys Happy Hour is our budget pick:

• Price: For only $34, the Happy Hour is the most affordable pick in the article. Our testers loved the competitive pricing, describing it as a massive bargain for the well-designed and versatile butt plug. Everything from the choice of materials to the practicality and impressive dynamism made the $30 price a bargain for beginners and sex toy collectors looking to add a knotted toy to their collection.
• Design: The design was another reason we chose the model. We loved how the tapered build enhanced the user experience, making the model beginner-friendly. In addition, the squishy silicone finish and knobby knot offered an excellent balance, making the stroking action a little challenging and thrilling. Although simplistic, the upgraded longer neck and phallic shape offered a gentle stretching experience for beginners and experienced users.
• Versatility: SquarePegToys Happy Hour Plug is the most dynamic model we tested. Its availability in eight different sizes meant everyone, regardless of their experience, had something to work with. In addition, the waterproof material was easy to clean and aquatic-ready, so that you can enjoy bath and shower play. The best part was that the silicone warmed to match your body temperature, making the experience more realistic.

3. Beowulf Fantasy Dildo: Great for Size!

Why we love Beowulf Fantasy Dildo:

Size queens will be excited to test their limits with the Beowulf Fantasy, a canine-shaped powerhouse with a raw and animalistic edge that makes for exciting solo play and partnered sex. Our testers loved the pronounced knot towards the center because it offered intense stretching. Notably, it’s also available in multiple sizes to ensure everyone gets the most appropriate model regardless of experience and mood.

The impressive versatility made Beowulf ideal for solo users and couples. More importantly, its availability in multiple sizes offers variety, allowing users to match their sexual desires with the right size and shape. You can also add accessories to your purchase, including a Vac-U-Lock hole to use the dildo with a harness or suction cup base. More importantly, you can customize the material’s density to balance comfort and practicality.

Pro Tip: After testing numerous models, we firmly believe picking medium firmness makes the most sense. The density offers excellent balance, allowing for a gentle stretching experience without discomfort.

The design was another feature that made us grow fond of the Beowulf Fantasy dildo. The larger sizes might be overwhelming for most people, but the variety means there’s something for everyone. We reviewed the medium size (10.5″ insertable length and 9″ circumference around the knot), and the feeling of fullness was satisfying. It took a while to get over the hurdle, but Jessica and I enjoyed the exciting thrill,” says Rachel Sommer.

The tapered design significantly enhanced the user experience and promoted a gentle stretching experience. Its pointed tip gradually grows into a massive knot, offering users a formidable challenge that’ll take lots of lube and patience to overcome (You can see the shape in the above image). Our testers also loved the T-shaped base because it improves handling and prevents unwanted travel during backdoor exploration.

“I loved the ridges on the shaft and subtle texture just before landing on the massive knot,” says Sandra Larson.  “The well-thought-out resistance from the knot makes the stroking sessions thrilling.”

The stimulations were another highlight of the review. I don’t know how to describe the feeling, but it felt like an overriding fullness that bordered on an addiction. According to Rachel Sommer, the gentle pressure gradually builds up into intense fullness as the dildo slides into the vagina or anal opening. “The excitement was intense, and the stroking action offered enough pleasure to make you squirm in excitement.”

The user experience depends on familiarity and beginners will find it challenging to get over the knob unscared. We found penetration blissful because of the tapered shape. In fact, the mental hurdle was more challenging than the physical one. However, once you’re past the mental fight, Beowulf becomes intuitive quickly.

The build quality was rated as above average. The brand uses platinum-cured silicone, the best sex toy material, so you can be sure it’ll last a long time. Cleaning the material was straightforward, and its adaptation to body temperature helped make the experience realistic. There was no foul smell or discoloration, and the consistent finish made it worth the time and money.

Minor issues we found during testing:

Our primary concern was the rate at which the material picked up dust and hair. You must clean the dildo before use because it’ll probably have picked up dirt and lint during storage.

Beowulf isn’t ideal for first-time sex toy users. Even the smallest model is 9″ long and 8″ wide (circumference), which is overwhelming for people without fantasy dildo experience. We recommend avoiding these pieces if you don’t have prior experience.

Why Beowulf Fantasy Dildo is the best large knot dildo:

• Design: The massive size was the main reason we picked the Beowulf as the best option for size queens. We loved how the shaft gradually widened towards the gigantic knot in the middle. Users will enjoy the formidable challenge that takes time and lots of lube to get past. Its T-shaped base simplifies the user experience and prevents unwanted travel, while the thick, meaty body inspires an addictive feeling of fullness that other fantasy toys struggle to replicate.
• Build Quality: Having reviewed multiple fantasy dildos, we loved how Beowulf’s designers used the best sex toy material, platinum-cured. The well-selected material and impressive attention to detail improve safety and durability. Cleaning was straightforward, and its waterproof design lets users take the fun to the shower or bath. More importantly, there was no foul smell or discoloration, with the consistent finish feeling incredible inside the vagina.
• Versatility: Beowulf’s availability in multiple sizes makes it among the most dynamic picks in the article. Singles and couples can make the most of the experience with its compatibility with other accessories, like the Vac-U-Lock hole, which allows users to enjoy hands-free fun using a suction cup base or harness.

• Material: Silicone
• Insertable Length: 9″ – 13″
• Circumference: 8″ – 12″ (knot)

Pros:

• Impressive versatility.
• A well-thought-out design.
• Multiple sizes.

4. njoy Fun Wand: Metal Knot Dildo!

Why we love njoy Fun Wand:

Among the metal dildos we tested, the njoy Fun Wand stood out because of its elegant and practical design. While it’s recommended for the more experienced folks, most users will enjoy the weighted feeling and differently sized bulbs on either end. Stroking the bulbous ends offers an incredible thrill, laying the foundation for intense orgasms.

Unlike other metal dildos we tested, we found the njoy Fun Wand to be more impactful. Everything from the weighted body to the slimmer size offered excellent balance, making it easy to manipulate the angles for maximum enjoyment. The curved shaft and rounded bulbs provided more surface area, making it easy to target specific spots inside the vagina.

Its stainless-steel finish allures the eyes. It’s one of those pieces that looks and feels expensive without the cliché multi-color design. More importantly, stainless steel is one of the best sex toy materials, boasting impressive durability and ease of cleaning.

The unique design with a double-headed approach offers more play options than regular models. Our testers loved that both heads had a distinct size and shape because it meant we could switch between the two depending on the mood and pleasure needs. Beginners can use the smaller size and gradually build up the courage for the bigger one. Other users also enjoy the foreplay effect of the smaller head. “Jessica and I always start with the tiny head, using it to get the vaginal muscles ready,” says Rachel Sommer. “I’ve also read of some users preferring the more palatable head for anal exploration.”

njoy Fun Wand’s 10-inch curved shaft offers a sufficient surface area for better handling. Although the stainless steel felt a bit slippery and containing it proved a tough ask, the extended length offered a much-needed reprieve.

Minor issues we found during testing:

Unfortunately, the Fun Wand isn’t ideal for people with weaker hands or mobility issues. Manipulating the angles and positions using the weighted toy can be challenging.

In addition, the stainless-steel toy is recommended for more experienced users. First-time and intermediate users will find it challenging.

Why njoy Fun Wand is the best metal knot dildo:

• Design: njoy Fun Wand’s ergonomic design was the primary reason we picked it as the best metal knot dildo. Unlike other models with a knot in the center, the piece has two knots on either end. The two uniquely designed bulbous ends provide variety during use, allowing you to switch between the gentler and more intense sensations. Our testers loved the banana-shaped design because it enhanced handling and also made it easy to target specific spots.
• Stimulations: While some reviewers were wary of the non-vibrating design, we were excited to try out the weighted build. Our team highlighted how the metal dildo offered a unique blend of form and function, allowing for intense internal orgasms with minimal hand movements. The distinct heads allowed users to switch between intense and gentle sensations. Whether you want to use the smaller one for foreplay or anal exploration, there’s something for everyone.

If you want to see what the njoy Fun Wand looks like and how to use it, please watch our unboxing and demonstration video below:

Features:

• Material: Stainless Steel
• Length: 10″
• Circumference: 3.5″ & 5″ (head)

Pros:

• Ergonomic banana-shaped design.
• The weighted body amplifies the sensations.
• Glowing stainless-steel material.
• The model is 100% waterproof.
• It’s temperature-responsive.

Cons:

• People with mobility issues will find using the model challenging.
• Reserved for experienced folks.

Other Good Alternatives

The Growler is a good option for people looking for an inflatable dildo. It has a firm inner core and a soft outer skin, offering a blend of realism and functionality. Our testers loved that the knot had a cushiony feel from the air trapped between the two materials. Although the size offered a challenge, the cozy feel meant it only took a bit of lube and patience to get over the hurdle.

Notably, Growler is available in multiple configurations. These models compress down to allow for penetration and quickly pop back in shape once inside, making for a remarkable feeling of fullness.

What is a Knot Dildo?

A knot dildo is a phallic-shaped sex toy designed with an iconic ridged shaft in the middle. The idea is to mimic fantasy creatures, with the knotted centerpiece adding a new dimension of pleasure that culminates in intense vaginal stretching. Plus, you can find numerous shapes and designs, including dog knot dildos, alien monsters, and dragon dildos.
