A concave cut creates a slight depression in the wood, which encourages the tree's bark to grow inward and over the wound as it heals. This results in a smooth, seamless scar rather than a protruding knob, preserving the aesthetic structure of your bonsai.

The 205mm (8-inch) length is a standard, versatile size that provides excellent leverage for most medium-sized bonsai. It is substantial enough to handle thicker branches while remaining precise enough for detailed work on smaller specimens.

To keep the blades cutting cleanly, wipe them down with a light oil after each use to prevent sap buildup and rust. Avoid cutting wire or overly hard, dry wood, as this can chip the precision-ground edges.
