The MTech Grenade Neck Knife has a 2.25-inch double edge stainless blade in a spectrum finish at 4.5 inches overall in a spectrum stainless handle shaped as a grenade and a black molded plastic neck sheath.
The spectrum finish is a thin oxide layer that refracts light into shifting colors rather than a paint or dye, so the shade changes with the viewing angle and cannot chip off. The grenade-shaped handle is the novelty here, with the moldings doubling as grip texture.
A double edge means both sides are sharpened, which suits piercing but rules out placing a thumb on the spine for pressure. At 4.5 inches overall it hangs from a cord under a shirt without printing through, and the molded sheath holds it inverted. Explore more Boot and Neck Knives.
