American Cutting Edges 70206-A is a light duty small breakaway knife. The breakaway is a very popular style of utility knife. Scored sections of the blade allow the user to “breakaway” used portions of the blade and expose a new sharp cutting surface. These blades are available in scored and non-scored versions. The two most common sizes are 9mm width and 18 mm width blades. If you like a disposable option for safety or a reusable knife, use after use with comfort grips and heavy duty metal frame construction.
