Among the 0454′s innovations is the first three-part Composite Blade. The proprietary Composite Blade process combines several steels into a single blade. In this case, Zero Tolerance put CPM D2 on the cutting edge and spine while 14C28N stainless steel forms the angular design through the middle of the blade. The three parts are laser cut like pieces of a jigsaw puzzle, then permanently braze welded together.
This remarkable Composite Blade is paired with 3D-machined carbon fiber handles that are lightweight, yet incredibly strong. For reliable blade lockup, the 0454’s sub-frame lock has a titanium lockbar with hardened stainless steel lockbar insert. The blade opens manually with a flipper and the KVT ball-bearing system. Strong blade detent gives the opening a powerful, professional feel.
Every detail of the 0454 is sculpted—from pocketclip to backspacer. A handsome, oversized pivot is the final touch on this impressive knife.
