Zero Tolerance Knives and Rick Hinderer teamed up to create the new Zero Tolerance ZTO566. The ZT0566 has an incredibly tough frame-lock design that features a blade made from ELMAX. With almost no impurities in the steel the knife's blade can be sharpened to extreme levels and also offers excellent edge retention, strength, and toughness. The blade deploys through the use of thumb studs that also function as blade stops.
For a secure grip, the handle is textured G-10 or carbon fiber with a sturdy frame lock and lockbar stabilizer. The ZT0566 is also equipped with a quad-mounting system so users can choose tip-up/tip-down, left or right handed carry. The clip is designed to allow for deep pocket carry as well for increased concealment.
