A bucksaw is a hand-powered frame saw generally used with a sawbuck to cut logs or firewood to length (bucking). Modern bucksaws usually have a metal frame ("H" or "C"-shaped) and a removable blade with coarse teeth held in tension by the frame. Lightweight portable or foldable models used for camping or back-packing are also available. It is often referred to as a bow saw in the North American hardware market, but that term traditionally refers to a different type of saw with a wooden frame.
A bucksaw is a crosscut saw, it is designed to cut across the grain. The width of the blade is constant from the teeth to the back. It is meant to cut wood fibers that are in tension and is thick so that it is more difficult to bend on the push stroke. They can be either a one or two-man saw. Coopers often use bucksaws in their work.
