Zero Tolerance Knives Reviews

With a longstanding reputation for reliability, durability, and value, Zero Tolerance Knives has earned outstanding feedback and reviews from satisfied hunters, outdoorsmen, tradesmen, and survivalists who use our high-performance blades in the field.

For years I carried a Zero Tolerance 0350TS knife on jobsites and camping trips. The Tiger Striped DLC coated S30V steel blade holds an edge incredibly well, even under heavy use. I've used it to slice through wood, strip wires, cut rope and even dress game without an issue. The textured G10 handles provide a solid grip, so I never feel like I don't have control. After 5 years of hard use, my 0350TS still looks and performs like new thanks to the durable materials. One time, I accidentally dropped the knife from a second story ledge onto a concrete slab but it didn't even chip or dull the blade. I've also used it to baton wood and pry apart material without any damage whatsoever. The quad mount pocket clip is convenient for tip up or tip down carry too. For me, Zero Tolerance knives represent the pinnacle of functional design and indestructible construction.

As a busy executive, I like carrying a slim, lightweight folder that can handle daily tasks. The Zero Tolerance 0450CF is perfect for me. The carbon fiber and titanium handle looks sleek and feels sturdy, while still fitting comfortably in my smaller hand and pocket. The drop point S35VN steel blade retains its razor sharp edge through weeks of opening packages, cutting fruit at lunch and other office tasks without needing sharpening. I also appreciate how smoothly and securely the frame lock allows the blade to glide open while preventing accidental closure even when I'm rushed. The pocket clip is reversible for left or right hand carry as well. For an elegant yet extremely functional EDC knife that can stand up to regular use, Zero Tolerance delivers exactly what I want. I've tried other luxury brand knives but the 0450CF is hands down the best combination of beauty, ergonomics and performance.

Jennifer Wu

Business Executive

Reliability and performance are non-negotiable for me as a police officer. I trust my life to my duty gear, and Zero Tolerance knives have never let me down. The 0808's stout 3.5 inch S35VN steel blade can pierce and slice through almost anything while resisting chips and corrosion even after getting wet frequently on the job. The flipper allows swift ambidextrous opening if needed in action, and slides back smoothly when I don't deploy the blade fully. The G10 handles provide a secure grip in any conditions, wet or dry, gloved or bare handed. After 18 months of duty carry, my 0808 still operates smoothly and looks barely used despite being dropped, rained on, and used to pry and dig on tough calls. I've tried several other tactical knife brands, but Zero Tolerance clearly engineers their knives to withstand tough daily use while providing flawless function in critical moments. I won't carry any other brand on the job.
