The Chad is Kunwu's hardest knife, literally. Kunwu Knives grinds its PM60 sheepsfoot blades to 66 to 69 HRC, a range almost nothing in production folders will touch, and hangs them on the XT Lock crossbar behind a textured thumb stud. The full-size Chad runs 3.77 inches of blade at 8.07 overall in diamond textured titanium, orange peel titanium, or carbon fiber; the Compact Chad brings the same profile down to 3.11 inches for lighter pockets. Both carry ambidextrous tip-up clips, and nothing else in the Kunwu catalog matches their edge-holding brief.
A powder metallurgy high-speed steel that Kunwu heat treats to 66 to 69 HRC, several points beyond where premium stainless like Elmax typically runs. The payoff is edge retention that borders on unreasonable and the ability to hold a thin, crisp edge through hard use. Our comparison of every major knife steel shows just how far outside the mainstream that hardness sits.
