The invention of CONCAVE CUTTER by MASAKUNI was an epoch-making event in the history of Bonsai training tools. Ever since its debut, MASAKUNI's No.16 has always been the leader of the CONCAVE CUTTER in Japan. By this tool complete branch cutting is made by only one action. That is; CONCAVE CUTTER bites a branch completely from its base and cuts into the branch base to make the cutting end concave because of its special blades' form. This concave cutting is good for trees, because it brings the quick and beautiful recovery of the cutting end. Since the concave cutting is very important not only for then but more important for future, it is inevitable to choose the best quality cutters from the beginning. MASAKUNI has some types of CONCAVE CUTTER as the series of No.16. Newly developed Nos.716 and 816 which have spherical blades, will bring more beautiful concave cutting.
