SUWADA Knob Cutter, 205mm

About this tool

The SUWADA knob cutter is used to remove knobs or swellings that develop on the trunks and branches of bonsai. As the point where the cut is made is cleanly gouged, using this tool accelerates the reproduction of callous tissue while completely removing unsightly knobs. The cutter’s characteristic concave blades are an original SUWADA design.


SUWADA started producing bonsai tools around 50 years ago with only one type of branch cutter. Responding to the diverse needs of bonsai enthusiasts not only in Japan but around the world, they increased their range of cutters and pliers. All bonsai tools are hand finished by local skilled craftspeople in the Niigata Prefecture of Japan. SUWADA's bonsai tools have achieved the highest reputation among bonsai professionals and enthusiasts around the globe.
