From the Manufacturer
As pull saws go, Gerber Exchange-A-Blade Saws more than hold their own. The stainless steel blades are as sharp and durable as the dickens, whether you're using the coarse blade on wood or the fine blade on hardwoods or big game bones. After all, they're designed to be 1/3 more efficient than typical handsaws. Include one of these in your gear, and you're good to go.
