A Two-Gate Instrument — Flared Ridge Up Top, Locking Knot Below
Lockjaw fuses two distinct fantasy archetypes into a single instrument: an equine flared head for ridge-pop entry, a canine-style spherical knot for locked retention. Stroke through the rim, sink past the knot — and the knot holds you there until you choose to break the seal.
Key Features
- Flared Equine Head — Wide, irregularly ridged flange with a longitudinal groove down the front. The rim pops cleanly past the sphincter on entry, then registers a clear "Ridge Pop" on every withdrawal.
- Spherical Locking Knot — Ball-shaped expansion at the base, max diameter 4.8–7.4 cm depending on size. Once seated, the sphincter contracts behind the knot and holds it in place — physical retention, not muscular effort.
- Bold Veined Shaft — High-relief vascular texture wraps the entire shaft and knot. Each thrust delivers continuous, irregular friction across the canal wall — coarse, organic, never uniform.
- Pleated Transition Collar — Wrinkled ring section bridges the knot and base, adding a tactile checkpoint between the locked phase and the seated phase.
- Realistic Testicle Base — Anatomically modeled scrotum base provides counter-anchor mass and a hard depth stop. Stable for hands-free harness or grip play; not suction-cup mounted.
- Body-Safe Construction — 100% platinum-cured silicone, Shore 00-30 single density, non-porous, phthalate-free, fully autoclavable.

Diameter is calculated by dividing the maximum circumference by π (3.14) — the value represents the average cross-sectional width, since the body is not a right cylinder.

Who It's For
- S — Intermediate users with prior textured-toy experience, ready for a 4.8 cm knot and ridge-pop entry.
- M — Advanced users comfortable with 6.0 cm knot retention and 20.5 cm insertable depth.
- L — Expert-tier — 7.4 cm knot, 25 cm insertable depth, full veined-shaft load.
Not recommended as a first dildo. Generous water-based lubrication is required for knot insertion and removal.
Care
Wash with mild soap and warm water before and after every use. Boil or autoclave for full sanitization. Pat dry, store flat, away from other silicone products. Use only water-based lubricant.
