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. 10 mL bottle with needle applicator USA
