Zero Tolerance - Carbon Fiber Folding Pocket Knife 3.25" Drop Point Steel Blade

This sophisticated ZT offers a robust combination of durable, premium-quality materials. The blade steel is S35VN for exceptional toughness, wear resistance, and edge retention. The S35VN blade is DLC coated for matte-black good looks and enhanced performance. The front handle scale is carbon fiber, balancing the knife’s solid construction with lightweight convenience. The DLC-coated titanium back handle offers a secure frame lock—so you can always cut with confidence. 

As an extra visual touch, ZT has added two emerald-green anodized-aluminum tube spacers that are especially eye-catching, standing out against the black handle. The 0450CF takes advantage of ZT’s KVT ball-bearing system to enable smooth, easy opening for either left- or right-handed users. A left/right reversible pocketclip rounds out the 0450CF’s basic feature set.

Attractive Blade Coating

Diamond-Like Carbon (DLC) coating is often even tougher than the blade steel underneath it. DLC-coated blades offer extra hardness, high corrosion resistance, excellent wear resistance and a low friction coefficient so particles do not easily attach to the blade. DLC coatings display properties similar to a natural diamond that add beauty and attractive shine.

Fast Deployment

Using 'caged' ball bearings for smooth blade deployment and overcoming stronger knife detent, the KVT Ball-Bearing Opening System makes one-handed knife opening fast and easy without the need of a mechanical assist. Ball-bearings surround and freely rotate around the pivot. When the user pulls back on the flipper, the blade rotates out of the handle as the ball bearings roll into place.

Secure Locking System

Kershaw’s frame lock design makes knives safer, securer, sturdier and quicker for one-handed blade deployment. The knife handle, or frame, has two metal plates on either side of the blade, and when open, the lockbar butts up against the blade’s backend to prevent blade closure. To close the knife blade, push the frame to the side to unlock the blade and fold the blade back into the handle.

Manual Flipper

Flippers on manual-open knives require user to push with quick strength until blade deploys. Some manual flippers disappear when blade deploys, others become a finger guard. Manual flippers appeal to inexperienced users as well as experienced users who prefer a classic, old-style opening. In both cases, ambidextrous flipper works as index finger applies pressure while closed knife sits in palm.

Durable Handle

A reinforced polymer of thin strands of carbon tightly woven, carbon fiber is tremendously strong yet lightweight. Strong weaves of bonded carbon atoms are used to compose carbon fiber in both Kershaw high-end knife handles and Zero Tolerance premium materials. With solid strength, wear resistance and corrosion resistance, carbon fiber is an excellent, high-performing, high-quality knife handle. Titanium is a lightweight metal alloy and it offers excellent corrosion resistance. Heavier than aluminum but still lightweight and strong, titanium is a very sturdy material often used in knife handles, locking liners, or as a blade coating to enhance performance. Titanium is a sleek, stylish, premium material

Convenient Pocketclip

Kershaw designs pocketclips to fit specific knives according to their weight, intended end use, size, style and hardware. Some knives have multiple carry options, others are more streamlined. A pocketclip with tip-up carry is positioned so the closed knife carries in the pocket with the tip of its blade pointed upwards. A reversible tip-up or tip-down pocketclip allows user to change tip position.
