Hasamiya Ichiban Traditional Thatched-Roof Straight Trimming Shears 240mm [Yasugi Yellow Paper Steel / 450mm Oak Handle / Hand-Forged / Twist Blade / Urasuki Hollow Ground / Rivet Joint]

Description

Crafted under the original Hasamiya Ichiban brand, these specialized, traditional masterwork shears are engineered specifically for trimming, shaping, and flat-finishing thatched roofs (Kayabuki Roofs) as well as heavy-duty landscaping operations. Completely hand-forged from scratch by skilled Japanese blacksmiths, they feature a classic straight blade design (Sugata-Ba) engineered to deliver powerful, precise, and broad shearing action across dense plant materials.

Forged using premium Yasugi Kishi (Yellow Paper Steel), these 240mm heavy-duty blades deliver a clean, decisive bite with minimal arm strain, while allowing for easy sharpening and long-term edge maintenance. The blades feature a traditional hollow ground back (Urasuki) combined with Twist Blade alignment to minimize friction and prevent sap buildup. Paired with a 450mm Japanese white oak handle (total length 815mm, weight 1,520g), this robust build provides powerful leverage, optimal plane control, and historical Japanese forging excellence for professional thatch crafts, master landscapers, and arborists.
