Knot Dildos

A knot dildo is a fantasy sex toy featuring a terminal bulge, the knot, at the base of the insertable shaft that widens beyond the shaft diameter and creates a locking sensation at full depth. The anatomy is drawn from canine mating biology and is the defining feature of the canine dildo and werewolf dildo category. Our knot dildos are cast in platinum silicone across single knot, double knot, dual layer, beaded and spiral formats.

What is the difference between a single and double knot dildo? A single knot dildo carries one terminal knot bulb, a single defined girth event at maximum depth. A double knot dildo carries two sequential knot bulbs: the Duovoor delivers a 4.5cm upper knot followed by a 7cm lower terminal knot, creating two locking events during depth traversal. The Noxveer dual layer carries a side-by-side double knot bulb as a structurally distinct alternative to the sequential double knot format.

What is a dual layer knot dildo? A dual layer knot dildo uses two different silicone firmnesses in a single casting: a firm platinum silicone inner core that maintains shaft structure through the knot engagement, and a softer outer layer that compresses dynamically during insertion. Five designs in the range use dual layer construction, including Omnvoor, Kraevoor, Zelvoor, Noxveer and Sylvex. No single-material knotted dildo produces the same dynamic dual-response sensation as a dual layer format.

For a first knotted dildo, compact single knot designs are the most accessible entry. The Curvoor at 5.4cm knot with curved shaft and the Clavoor at 6.4cm knot in compact deep violet are the smallest knot diameters in the range. Both have moderate shaft diameters with the knot as the primary girth event. Avoid dual layer XL and double knot formats initially, as the Omnvoor and Duovoor require significantly more preparation than compact single knot designs.

Yes. Every knot dildo in the collection is cast in platinum-grade silicone: non-porous, hypoallergenic, free from phthalates and latex the same material
standard as Bad Dragon. Platinum silicone does not harbour bacteria between uses when cleaned correctly. Clean with warm water and toy cleaner after each
use.

Boil-safe for full sterilization. Water-based lubricant only never silicone-based on a platinum silicone knotted dildo.

Yes all designs in this collection include a suction cup base that works on smooth non-porous surfaces, which makes the format fully functional for solo hands-free use.

The suction base also means the toy stays positioned correctly during use, which matters more with knot designs than with standard dildos because the knot requires consistent pressure application rather than active thrusting.

For partner play, the knot format works well with manual control a partner can manage pace and pressure through the knot more precisely than hands-free methods allow. Communication matters more with this format than most others: the knot creates a distinct physical threshold that both partners need to be aware of and working with deliberately.
