These Japanese trunk splitter shears are designed for advanced bonsai modification work. Their specific geometry allows them to apply strong pressure to split wood, ideal for working on jin, shari, or thick branches.

Unlike traditional shears, their blades align almost in a straight line, which generates superior cutting power. This tool is particularly effective for splitting branches, working with hardwood, or creating natural effects on deadwood.

It is also used to open wood to bend or transform it without damaging essential fibers. An indispensable tool for enthusiasts wishing to sculpt and shape their bonsai with precision and creativity.
