KPL Original was designed from the ground up to work better on knives than anything else. We formulated the product to seep easily between low tolerance parts while remaining highly protective of bearings, races, detents and blades. Whether you are obsessed with fall-shut framelocks, into buttery bronze washer pivots, or just the kind of person who takes great care of their tools, KPL Heavy is a higher viscosity version of the KPL you know and love. KPL Heavy is highly thixotropic/shear thinning formula designed specifically for knife detents and detent tracks. Ordinarily gel-like, each time your lock mechanism clicks into place, the shock refluidizes KPL Heavy allowing it to refresh the lubrication of your detent ball. When sitting without shock/shear, the KPL heavy regains its higher viscosity so it stays put near the detent. The unique properties of KPL Heavy revolutionize detent care. Eliminate scratchy detents, lubricate less often, and trust KPL Heavy to remain SUPER washout resistant.
