6" Spherical Knob Cutter by Yoshiaki


Known in Japan as Kobu iri Hasami, these cutters are designed for removing trunk knobs and roots.  The head is shaped like a ball, hence the name 'Spherical'.  They produce a hollow, circular cut that heals quickly and with a minimum of scarring.

A smaller version that allows use for smaller trees and tighter areas.  Used to create a concave cut into the trunk where a branch was.  This allows the tree to heal and clause folds into the depression so that the trunk does not have a raised area where the branch once emerged.

Length - 6 inches


Made in Japan
