Professional G-series hacksaws are equipped with a sheath with a swivel buckle. The steel blades containing a high percentage of carbon, are covered with hard chromium to resist rust and increase branch penetration. The clear and precise cut makes the wood surface smooth and flat, preventing infections and allowing fast formation of scar tissue on the branch. Teeth are sharpened in 3 planes and pulse-hardened to maximize sharpening life. The special blade processing, called “surface flaring”, is designed to improve branch penetration by drastically reducing friction.
