Bonsai Knob Cutter by Roshi Tools 6.8" (180 mm)
Roshi high carbon steel bonsai tools are known for precision cutting, durability and excellent prices. 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 bigger bites than expected.
