The CRKT Otanashi no Ken folder knife is a James Williams design. Built with a black G10 handle and a deep carry pocket clip for inconspicuous carry, the knife is patterned after the Osoraku style blade of the 16th century. Boasting a non reflective black coated 4.52" blade, the classic Samurai design blade gives outstanding penetrating power and exceptional slashing performance. The knife uses the CRKT patented* LAWKS® safety that creates a virtual fixed blade when the blade is opened and locked. This gives you the penetrating power of a big fixed blade in a small tactical folder. SPECIFICATIONS: Blade: Length: 4.52" Thickness: 0.16" Steel: AUS-8, 58-59 HRC Open: 10.13" Weight: 6.4 oz.
