The Fox MK Rescue Tool is a multi-tool in a fixed karambit form, designed by Doug Marcaida and produced by Fox Knives in Italy. The 2.25″ N690 stainless steel consists of a chisel tip and a seat belt cutter. The “blade” of this innovative tool features cutouts that function as 6-sided wrenches, 3 sizes in all. The included Kydex sheath also includes a Torx wrench for quick adjustments. A black Cerakote coating provides extra protection for the blade itself.

A reversible pocket clip is included and hugs the sheath. If belt carry is not your thing, the back ring doubles as a carabiner, expanding the attachment options of this innovative tool.

N690

Bohler N690 steel’s ability to withstand stress is a favorite choice for knife makers. It is used to make outdoor knives including, tactical, camping, hunting, and bushcraft knives. Known for its exceptional balance of hardness, corrosion resistance, and edge retention, N690 is a steel alloy with a  unique composition, including a high concentration of carbon, nitrogen, and chromium, provides outstanding durability and performance in various cutting tasks.

The cobalt-alloyed N690 by Böhler  is a very reliable stainless steel Fox uses for a wide variety of projects. The fine-grained N690, which ranks above 440C, offers convincing performance data in all areas. It is often sold as N690Co – the “Co” stands for cobalt and describes the exact same steel.
