420J2 stainless steel – corrosion-resistant and sharp
The 420J2 stainless steel blade offers a hardness of 51–54 HRC and a satin finish. The rust-resistant steel is particularly suited for keychain carry, where moisture and sweat are part of daily life. The MicroLock mechanism reliably locks the blade in the open position, preventing accidental closure.
S-Biner MicroLock – securely attached
The included S-Biner MicroLock with twist-lock attaches the knife securely to your keychain, backpack or belt. The twist-lock mechanism prevents accidental release – the knife stays where it belongs.
Compact and always within reach
At just 68 × 21 × 5.6 mm (closed) and 20 g, the Key Chain Knife is barely larger than a car key. Yet the 48 mm blade provides enough cutting surface for parcels, twine, film and light everyday cutting tasks.
