12" Spherical Knob Cutter Large Professional Grade by Joshua Roth


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.

This particular tool is great for "eating" away large branches on a trunk or any other need to remove large amounts of material.  This is a great tool to have when you need to finish off removing a large branch and create the concave cut into the trunk.
