The Zero Tolerance 0550 features a bullet-tough blade of Crucible's S35VN stainless steel with a roughed-up “stonewashed” finish. This ultra high-performance steel is a third-generation powdered steel designed to offer increased toughness over S30V, yet be easier to machine and polish. S35VN’s chemistry includes niobium, vanadium and chromium carbides. It is very clean with virtually no inclusion and offers an exceptionally uniform distribution of carbides. It is highly wear resistant and resists edge chipping and corrosion, too. In other words, this high-performance knife can take whatever you can dish out.
Designed by Rick Hinderer, the 0550 is a manual-opening knife yet can easily be opened one-handed with the ambidextrous thumbstud. The 0550 offers the user a secure grip thanks to the contoured handle ergonomics as well as the textured G-10 front handle scale. The back is titanium and is home to a super-secure frame lock with lockbar stabilizer to prevent overflexing of the lock.
For such a good-sized knife, the 0550 is surprisingly light and makes an excellent every day carrying blade. And, thanks to Zero Tolerance’s Quad-mount system, you can carry it tip-up or tip-down, left- or right-handed. The clip is also designed for deep carry, so it sits well down in your pocket.
