Product Description

The Zero Tolerance 0044 is a Dmitry Sinkevich-designed flipper built around a button lock mechanism and premium CPM-S90V steel, giving it a smooth, fast deployment and edge retention that outlasts nearly every other steel on the market. At 3.4 oz with a 3.20" blade, it carries a substantial, premium feel without becoming a burden in the pocket.

The blade is CPM-S90V, a super-premium powder steel known for exceptional wear resistance and edge holding, ground to a drop point profile with a working stonewash finish. It rides on ceramic KVT ball bearings for a smooth, fast flipper action, and locks open via Zero Tolerance's manual button lock, giving one-handed opening and closing with a firm, confident lockup.

The handle is 3D machined, weight-relieved titanium finished in a blue anodized stonewash, a lightweight and corrosion-resistant material that keeps the knife's overall weight down despite its substantial build. A deep-carry, reversible tip-up pocket clip supports left- or right-handed carry.

Made in the USA, the ZT 0044 is backed by Zero Tolerance's Limited Lifetime Warranty and their free factory sharpening program. Add the Zero Tolerance 0044BLU to your cart today and get the legendary service and fast shipping Knifeworks is known for.
