Deploy the blade quickly and easily, even in gloves, using the ambidextrous flipper. The ZT 0350’s blade is S30V stainless steel with stonewash S30V steel. This high-performance S30V blade is paired with black g-10 scales for a secure grip and excellent mechanical strength even under the roughest conditions. Mount the pocket clip in any of four ways: tip-up, tip-down, on the left side, or the right. There’s a pre-drilled lanyard hole for users who prefer to attach a lanyard.
