The SK Design PVA4 Designer Pivot Assembly is a premium solution for custom folding knife construction, crafted with precision by U.S. knife maker Steve Kelly. This high-performance pivot system features a heat-treated 416 stainless steel barrel paired with dual 6AL4V titanium screws—offering both strength and a refined, custom look.

Each titanium screw has a head diameter of 0.307 inches and is designed to seat cleanly into a 5/16-inch (0.312-inch) counterbore. The T15 Torx interface ensures secure installation and reliable long-term performance.
