Tobisho Ultimate Masterpiece Pruning Secateurs Custom Hiryu-Type Total Length & Blade :190mm/57mm Yasuki Special Cutlery Steel [Traditional Hand Forged from Scratch / Master Hand-Forged / Hollow Ground Back / Twisted Blade / Screw Joint]

Description

Handcrafted in Yamagata Prefecture by Tobisho (Tobizuka Shears Works), the Custom Hiryu-Type 195mm represents the absolute pinnacle of Japanese blacksmithing and precision shear engineering. Positioned at the very top of Tobisho’s catalog, this ultimate masterpiece is created for master craftsmen, arborists, and collectors seeking the purest cutting experience achievable in hand-forged tools.

The breakthrough feature of the Hiryu-Type is its Zero-Contact Clearance Construction (~0.2mm Micro-Gap). Unlike conventional secateurs where steel blades rub continuously against each other, the cutting blade and counter-blade of the Hiryu are engineered with a precise micro-clearance gap of approximately 0.2mm. This eliminates steel-to-steel friction and metal wear entirely, resulting in near-frictionless handle action, maximum energy transfer to the cut, and unprecedented tool longevity.

Forged from genuine Hitachi Yasuki Special Carbon Steel, the primary blade features an extra-wide, tapered spine that transitions into a surgical-grade edge. Combined with precision 3D concave hollow grinding (Urasuki) and custom crossover geometry (Hinari), the blade bites into live timber instantly and glides through with an effortless "cut-through" sensation. An internal shock-absorbing spring mechanism absorbs end-of-cut recoil, while a traditional genuine leather bottom latch provides a quiet, refined closure.

Note: Due to its ultra-fine, surgical-edge geometry, avoid twisting the shears or cutting dead, seasoned hardwood to prevent edge damage.
