The OXO Good Grips Folding Pruning Saw with Safety Lock has a sharp, hardened, SK5 steel blade with an aggressive tooth pattern that cuts on the push and pull strokes for smooth cuts of thick branches. The Saw features a Safety Lock which requires squeezing buttons on both sides of the Saw handle to keep fingers clear of the blade when it is folded down for storage. A steel blade guide at the butt end of the Saw protects the handle from damage when the Saw is folded closed. When locked closed, squeezing the buttons kicks the blade out slightly for quick and easy opening. The Saw also has a contoured, pressure-absorbing, nonslip grips with a smooth, cushioning gel pad that prevents blisters. Rust-proof aluminum construction makes this Saw both lightweight and durable.
