The M48 Cyclone Boot Knife condenses the fierce, tri-edged design of the original Cyclone Dagger into a compact and carry-ready format. Its 5 3/4” cast stainless steel blade features the signature spiraling edges that culminate in a needle-sharp point—engineered for deep penetration and lasting edge retention. Heat-treated to 1,030 degrees for a 48HC hardness rating, this blade balances dramatic form with uncompromising function. Crafted for dependable grip and control, the handle is made from glass-fiber-reinforced nylon and shaped for a secure, slip-free hold. A stainless steel glass breaker pommel adds emergency-ready versatility. The knife fits snugly into a custom-molded Vortec sheath, offering durable protection and quick access. At 10 1/2" overall, the M48 Cyclone Boot Knife delivers compact power you can count on.
