Perfect for precision cutting and trimming of paper and other light-weight materials; these knives create elaborate detailed cuts. The A-1 Aluminum Light Duty Knife (AA17960) features an aluminum barrel with two textured grip areas to prevent slipping. It comes with one A-11 carbon steel blade and a hard plastic safety cap. Replacement A-11 blades are available in either a re-usable plastic case of 5 (AA17981), or a bulk pack of 100 (AA17981100).
