KPL™ FEATURES
Make your Knife Better
KPL improves the action in your knife.
KPL is formulated specifically for high-end knives.
Protect Your Investment
KPL keeps dirt, metal particles, and grit "in suspension" so they don't cause grinding and premature wear. KPL actually cleans your pivot as you use it.
Ligtning Fast
The viscosity (thickness) of KPL keeps knife actions buttery-smooth without slowing them down.
It's Just Better
KPL's synthetic formula keeps dirt, grit, and contaminants in suspension to prevent wear and friction.
Compatible with ball bearings, bronze washers, teflon washers, IKBS, MRBS, nylon (nylatron), G10, micarta, titanium, and metals.
