These heavy-duty concave branch cutters have a sharp blade designed for cutting branches flush to the trunk. The spherical shape differs from the straight standard concave branch cutter by giving you extra strength during a cut and enabling you to create round edges when using with jins. Specifically for use for bonsai trees, the solid cut will reduce scarring and decrease healing time. Overall length of the spherical concave branch cutter is approximately 7 inches. Stainless steel construction. Made in Japan.
