The 0850 is a design collaboration between Dmitry Sinkevich and Todd Rexford. Originally a custom piece they brought to Zero Tolerance and introduced it as a production knife while keeping a lot of the high end properties of the knife. The blade is a CPM-20CV steel and has a sheepsfoot design. Black and blue carbon fiber scales with liners, cool backspacer and interesting design touches throughout the knife. Completely out of the box and different for ZT but it all works.
