Sågkanten

Sågkanten (Swedish for the saw edge) refers to the cutting portion of a saw blade—the edge and its teeth that engage the material being cut. The term encompasses the active edge, including the tooth tips, the gullets that clear chips, and, on some blades, the reinforced back. The geometry and condition of the sågkanten determine cutting performance, speed, and finish.

Tooth design and configuration strongly influence how the edge cuts. Different blades use different tooth shapes and spacing to optimize for materials and tasks. For woodworking, there are ripping teeth intended to remove material quickly and cross-cut teeth designed for cleaner, smoother cuts. Some blades combine both functions, and the set of each tooth (the outward tilt) along with bevel angles affects kerf width and cutting action.

Materials and maintenance are important for sågkanten longevity. Blades are commonly made from carbon steel, high-speed steel, or carbide-tipped steel for durability. Sharpening restores the edge and tooth geometry and can be done with a file or a grinding tool, depending on blade type. When teeth become dull or damaged beyond repair, replacement of the blade is often more economical.

Applications and use vary across tools. The term återknyter to the edge found on hand saws, backsaws, circular saws, jigsaws, and other cutting tools. The condition and design of sågkanten influence cutting speed, finish quality, and heat generation, making proper selection, use, and maintenance essential in carpentry, woodworking, and metalworking contexts.
