A Unique saw blade can be used in most of the heavy-duty (l type) cutters. It turns a utility knife into a saw. Ultra-sharp, premium-grade, Japanese-style cross-cut blade cuts smoothly on the pull stroke. This saw blade features a convex curved tip to allow you to cut into the surface so you can begin a cut from anywhere on the surface, not only from the edge. The uniquely designed raked teeth help keep sawdust from building up in kerfs. The blade is made from carbon tool steel and hardened by a special heat-treatment to obtain optimum sharpness, durability, and wear-resistance. Great for woodcraft & hobby projects, model-making, or other fine work. This saw blade will fit into heavy-duty screw-lock utility knives.
