Koyo Professional Grade Spherical Knob Cutter 8.25"

Knob Cutters are designed for removing unsightly knobs from trunks and branches without leaving protruding callous when the cut heals. They can also be used to further hollow out the cut after a concave branch cutter is used. Be careful not to overdue it with your knob cutter, they can take out more material than you expected.
