As with clamps, it seems you can never have too many utility knives. This is an excellent deal on a set of five 9mm and five 18mm good-quality auto-loading utility knives.
Each knife has a stainless-steel barrel, a cartridge containing five segmented (snap-off) SK-5 blades and a co-molded rubberized handle. The large knives are 7" long and have a blade-clamping shoe that locks the blade securely in place for heavy cuts. The small knives have a contoured grip and are 5-1/2" long.
At less than $2 each, these are great value. Available while quantities last.
