The Primo is the second passenger in Kunwu's Vancron program, and the broader-shouldered of the two. Kunwu Knives grinds a 3.42 inch blade standing a full 1.55 inches tall from the nitrided powder steel at 63 to 65 HRC, then seats it in a TC4 titanium frame lock at 7.75 inches overall and 5.29 ounces. Bead blasted grey, raindrop stonewashed, and raindrop PVD black handles carry satin, stonewashed, and DLC blades, with that raindrop texture giving the Primo its signature look inside the wider Kunwu catalog.
Blade real estate against straight-edge commitment. Both run Vancron at 63 to 65 HRC on titanium frame locks within a quarter inch of each other's footprint. The Kunwu Cochise goes all-in on a cleaver profile, while the Primo spreads its steel into the tallest blade in the lineup for a bigger working surface behind the edge. The steel is a wash between them, and our steel rankings cover why Vancron earns its exotic billing either way.
