The Kubey Boxer KU407F is a compact EDC folder designed by Maksim Epifantsev, distinguished by its transparent polycarbonate handle. The blade, made of Sandvik 14C28N steel, along with the Liner Lock and ceramic ball bearings, creates a visually lightweight and functional design for everyday use.
The 63.00 mm blade features a Sheepsfoot profile, a flat grind, and a satin finish. Manual opening is facilitated by a front flipper and a thumb disc, offering a choice between two opening methods.
Sandvik 14C28N and Vacuum-Cryogenic Hardening
The blade is made of Sandvik 14C28N steel, hardened to 60–62 HRC. Vacuum hardening combined with cryogenic treatment promotes high hardness, wear resistance, and stable steel properties during regular use.
Sheepsfoot, flat grind, and Satin
The Sheepsfoot profile provides good blade control and is ideal for precision tasks. The flat grind supports efficient cutting, while the satin finish gives the blade a subdued appearance.
Transparent Polycarbonate, Liner Lock, and Ceramic Bearings
The transparent polycarbonate handle partially reveals the knife’s internal construction and gives the model a distinctive, modern look. The design is complemented by gray stainless steel spacer rings and sandblasted steel structural components.
Ceramic ball bearings ensure smooth blade movement, while the Liner Lock secures the blade when fully open. The steel clip can be mounted on the right or left side in a tip-up configuration.
