The CRKT M.A.K.-1 (Multiple Access Knife) was designed by James McGowan, a professional firefighter and a knife designer. It is a rescue and rapid entry knife, made of tough 3Cr13 stainless steel. It has a blunt chisel pry-bar tip for opening doors and windows and a Razor-Sharp knife edge suitable for heavy cutting or hacking tasks. The heavily textured and grooved G10 scales offer an aggressive grip and allow control when wearing gloves. They can be removed for cleaning.
The M.A.K.-1 gives two window-breaking options. A twist breaker groove allows controlled breaking of automobile side windows, while a carbide tip butt breaker allows smashing of building windows or automotive back glass. An 8mm groove functions as a wrench for disconnecting GM-style side terminal batteries. The 2050 MAK-1 comes with a custom Cordura sheath with belt loop.
