SuperKnife 804 Mini Folding Utility Knife, Red. When the Super Knife's blade is dulled, it can be easily removed and replaced with a new, sharp blade. Super Knife will accept a wide-range of utility knife blades and the one-piece blade holder design insures the blade will not slip out under pressure. Following the same design features as the original SUPERKNIFE, the Mini folds to a mere 1 3/4'', safety locks open and closed, and holds mini utility blades. The quick release key chain lanyard insures you will never be without a razor's edge. Red anodized aluminum handle. Includes three (3) spare blades.
