ZT0550BLK: Model 0550BLK, Hinderer Design
Zero Tolerance Knives

The Zero Tolerance 0550 features a bullet-tough blade of Crucible's S35VN stainless steel with a tough black DLC coating. 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.

ZT 0550BLK
I use it as EDC. I call it as a pocket tank. That knife feels much more better in hands as it looks like at the picture. Clip is not titanium. It tooks about 1000 times opening and some lube to make that blade fly. Its opening pretty fast for the weight of the blade!The knife design to work in gloves because g10 plate is too rough for the skin. That model is one of the best for price and quality on the market. No bearings what makes knife more reliable for heavy tasks. Thx again for KC for excellent customer service!

Awesome knife that is truly a the top of my list. Well balanced & precision crafted. Great value in a knife that you can carry daily. KnifeCenter shipped quickly and if it wasn't for the USPS mishap on delivering would have had it in break neck speed.
