Concave Cutters - No Western Equivalent
Japanese concave cutters, also known as Mataeda Hasanmi, are necessary to style bonsai and pre-bonsai nursery stock. There are specifically designed to cut branches flush to the trunk and there is no western equivalent for Japanese concave cutters. This type of cut allows the wound to heal quickly and smoothly, and without creating an unsightly bump on the trunk of your bonsai tree. If you are a bonsai enthusiast, this is a bonsai tool you need to own.
