Known in Japan as Kobu iri Hasami, these cutters are designed for removing trunk knobs and roots. The head is shaped like a ball, hence the name. They produce a hollow, circular cut that heals quickly and with minimum scarring. The high carbon steel of this tool will keep a sharp edge indefinitely when properly used and cared for. Vinyl-covered handles provide a comfortable and sure grip with this professional quality tool. 5/8" blades, 8" overall length.
