Professional foldable saw with straigth blade, practical, easy to handle and safe thanks to its snap closure. 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. The teeth have been sharpened on three levels and have been pulse-tempered for maximum duration of sharpening. The special blade processing, called “surface flaring”, helps the blade penetrate the branch by drastically reducing friction. The ergonomic handle ensures a firm grip.
