 As compared with wood-cutting saws, the blades of musical saws are generally wider, for range, and longer, for finer control.They do not have set or sharpened teeth, and may have grain running parallel to the back edge of the saw, rather than parallel to the teeth.Some musical saws are made with thinner metal, to increase flexibility, while others are made thicker, for a richer tone, longer sustain, and stronger harmonics.
