Concave Cutters by Roshi Tools - 8" (203 mm)

Create cleaner cuts and more natural healing with the Concave Cutters by Roshi Tools. Designed specifically for bonsai branch removal, these professional-grade cutters create a shallow concave wound that promotes smoother callusing and helps scars blend naturally into the trunk and branch structure over time.

Their specialized jaw design allows you to work close to the trunk or branch collar, producing cleaner results than traditional pruning tools and preserving the long-term aesthetics of your tree.
