The Hiryu design is unique to Mr Yasuhito Tobiduka, who pioneered these secateurs in a quest to find a product which can be used for a full day of pruning, but which does not tire the hand muscles as much.
The deign works in a way where the two edges do not make contact, but work circularly in relation to each other. This allows for decreased resistance and easier pruning.
By applying grease to the grease holes, cutting performance is maintained. Hiryu secateurs also include two springs to alleviate the shock of constant opening and closing.
TOBISHO secateurs are hand-forged in the city of Yamagata, which is famous for its blacksmithing and iron casting. Mr. Yasuhito Tobitsuka is the 8th and current Master Blacksmith of TOBISHO. The company has a history of more than 200 years, with 80 years and three generations of specialisation in secateurs and pruning shears. TOBISHO secateurs are hand-forged in a slow heating process from single pieces of high-quality Japanese steel, and are therefore exceptionally sturdy with a sharp cutting edge.
