Professional folding hacksaw with a curved blade, practical, handy and safe due to the snap lock. 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 machining of the blade called “flared planes” facilitates penetration into the branch by radically decreasing friction. The ergonomic handle ensures a firm grip.
