Designed by renowned bladesmith Dmitry Sinkevich, the Zero Tolerance 0452CF is a revision of the award-winning 0454. The 4.1" blade is exquisite S35VN steel, among the very highest quality steels available for blade crafting. The handle is carbon fiber on one side, which makes it light to the touch, with a titanium framelock for toughness. If you're looking for a high-quality tactical folder with beauty and brains to match, the ZT0452CF could become your new main squeeze.
