Tronchese bonsai a taglio sferico semi-professionale 180 mm

What it is for

The spherical knob cutter bites into the wood and hollows it out: the round head enters the trunk and removes the branch collar, leaving a hollow instead of a stub. This is the step that decides how the scar will look. When you permanently remove a branch growing from the trunk, this concave cut allows the callus to close flush, without the unsightly swelling left by ordinary scissors or a flush cut.

It is also used to clean up old, badly cut stubs and to prepare the area before applying healing paste.

Who it suits

Intermediate and expert level. It is not a first-purchase tool: you need a trained eye to judge where and how deep to hollow, because the spherical cut removes more wood than it seems and on a thin trunk mistakes happen fast.

The 180 mm size makes it ideal for shohin bonsai and small to medium-sized plants, where the compact head works well even among dense branches. We recommend cleaning and oiling the blades after every session, especially if you have worked on resinous pine or juniper wood.
