The Zero Tolerance 0850 is an exciting Dmitry Sinkevich/Todd Rexford collaboration based on a spectacular custom piece the two knifemakers built together in 2016.

Dmitry and Todd had always admired each other’s work, so perhaps it was inevitable that they would eventually collaborate. They talked and agreed to work on a project together. Dmitry provided a drawing of an initial concept. Todd worked out the design details and décor. Together they went to work in Todd’s Colorado workshop, sawing, milling, sharpening, and polishing. Eventually, they built exactly two completely astounding knives. And sold them almost instantly.

Zero Tolerance decided that two was not enough. We talked with Dmitry and Todd and they agreed to work with us on a production version of their collaboration. The 0850 is the result.

The blade is CPM 20CV stainless steel with a two-tone, DLC coated & machine satin finish. This powdered metallurgy steel offers outstanding edge holding capability and corrosion resistance. The 0850 opens manually using a decorative aluminum thumb stud with a black DLC coat. The thumb stud is echoed by the unique aluminum backspacer that has been turned and sculpted, then black DLC coated. The handles that surround this unusual backspacer are built from a carbon fiber composite material.

To keep the weight down on this big folder, ZT added our patented Sub-Frame Lock with hardened steel lockbar insert. (The ZT Sub-Frame Lock is covered under US Patent 9,120,234.) A custom machined titanium clip with black DLC coating and pivot cap, and black Teflon®-coated hardware round out the look of this extraordinary knife.

This black carbon fiber & dual-finish blade version of the 0850 is a sprint run, built in limited quantity.
