Product details

Core Definition

Lockjaw is a two-gate silicone dildo: a flared equine head that clears the rim on entry, and a spherical knot below it that stays seated once past. Platinum-cured silicone at Shore 00-30, with a knot measuring 4.6 to 7.4 cm across depending on size.

How It Works

Ridge-pop entry. The head is a wide, irregularly ridged flange with a longitudinal groove down the front. The taper ahead of the flange keeps initial resistance low; the rim then clears the sphincter in one movement and registers again on every withdrawal, so the entry point is felt on both directions of the stroke.

Knot retention. Below the shaft sits a spherical expansion, 4.6 cm across on S and 7.4 cm on L. Once it passes, the sphincter closes behind the narrower collar and holds the shaft in place without muscular effort. Removal requires the same deliberate pressure as entry, so plan for it.

Continuous shaft friction. High-relief vascular texture runs the full length of the shaft and over the knot. The relief is irregular rather than repeating, so contact against the canal wall shifts through the stroke instead of settling into one pattern.

Who It's For

S suits intermediate users with prior textured-toy experience who are ready for a 4.6 cm knot. M and L are for advanced users already comfortable holding a knot in place at 6.0 cm and above. This is not a first dildo, and the L size at 25 cm insertable is not a size to work up to in one session. Generous water-based lubricant is required for both directions.

Care & Safety

Molded from 100% platinum-cured silicone: non-porous, phthalate-free and heat-stable. Wash with warm water and mild soap, or a dedicated toy cleaner, before and after every use; boil for two to three minutes for full sanitization. Use water-based lubricant only, as silicone lubricant attacks the surface. Dry completely, then store flat and away from other silicone items. Stop use if you feel pain, use a barrier when sharing, and keep away from anyone under 18.
