Williams Blade Design OZF 003 Osoraku Zukuri Folder 4.5"

The full-sized Osoraku Zukuri Folder makes its return from Williams Blade Design. The outer profile has been pared down while the blade length has been extended to a full 4.5”, creating a streamlined design that fits perfectly in the hand while maximizing usable blade length in the most discreet format possible. The handle features carbon fiber from FatCarbon, chosen for its ideal strength-to-weight ratio, paired with a titanium frame lock for uncompromising solidity. A 3/16” thick MagnaCut blade delivers outstanding edge retention and toughness. This model represents the pinnacle of the Williams Blade Design folding knife ethos.
