Custom ceramic bearings by Herman Knives with an upgraded design for ultra-smooth action. M390 steel washers are precision-turned, vacuum-hardened to 60 HRC, EDM-cut, wire-sliced to 0.6 mm, then hand-lapped to a 4000-grit mirror finish—all done in-house.
Ceramic & Carbide Components
Ceramic detent ball for crisp engagement
Tungsten-carbide lock insert and stop pin for maximum wear resistance
Refined Pivot
Three in-house parts ensure flawless rotation:
Phosphor-bronze bushing (self-lubricating, zero play)
Seven-petal clover screw to lock rotation
Vacuum-hardened Torx T20 screw (reapply Loctite after adjustment)
Enhanced Stability
A caged 16-ball layout prevents displacement and maintains silky-smooth performance.
What’s in the Box
Original wooden presentation box, microfiber cloth, Pruciak Protector Glide oil, and a bespoke stainless-steel screwdriver—each crafted by Herman Knives.
