This Felco 600 folding pruning saw, with its ergonomic handle and rust resistant hard-chromed blade, easily cuts branches up to 4 inches. To prevent binding and clogging, the folding pruning saw blade is thinner at the top and thicker at the bottom where the teeth are. This allows only the teeth to come in contact with the wood. This Felco 600 folding pruning saw is one handy tool that no gardener should be without. You'll love this handy saw.
