Zero Tolerance Knives

Zero Tolerance – Built Like a Tank, Carried Like a Pro

Zero Tolerance (ZT) makes hard-use knives with precision and polish, blending premium materials with industrial-grade strength. If you want a knife that’s overbuilt without being overkill, ZT delivers time and time again.

History

Launched in 2006 as a premium line under Kershaw and Kai USA, ZT set out to build knives tough enough for military and law enforcement professionals. Their early designs, like the 0301 with Strider and Ken Onion, established them as a go-to brand for serious users and collectors alike.

Since then, Zero Tolerance has expanded into sleek flippers, slicey folders, and collectible collaborations—all still made in the USA. Their commitment to fit and finish, even on the most rugged models, gives ZT knives a reputation for being as refined as they are reliable.

What They Offer

  • Premium Materials: Most ZT knives feature titanium, carbon fiber, CPM 20CV, and MagnaCut steels—nothing is off the table.
  • Bold Designs: Many models are collaborations with top designers like Dmitry Sinkevich, Les George, and Todd Rexford.
  • Made in the USA: Built in Tualatin, Oregon with precise tolerances and tight quality control.
  • Fan Favorites: Models like the 0450, 0562, 0462, and 0022 have built cult followings for good reason.

Whether you’re heading to the job site, the mountains, or just your mailbox, ZT knives are built to go the distance—and look good doing it.
