The professional pruning U series have its U handle grip. This type of hand grip makes olive orchard pruning practical and efficient. 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 length of the blade and special processing, called “surface flaring,” are elements designed to improve branch penetration by drastically reducing friction.
