The Zero Tolerance 0609 is a more compact version of the 0606CF Factory Custom collaboration from RJ Martin and Matt Martin. It offers a clean, detailed titanium handle with grip-enhancing machining and a bronze anodized finish. The 0609 is equipped with a CPM-20CV steel blade in a two-tone finish with satin grinds and stonewashed flats. This sleek folder comes complete with a See-Through Pivot (STP) designed by RJ Martin to allow you to "see through" it, adding another unique touch to an exceptional knife.
