Hado Shiosai 180mm Bunka SG2 Urushi Oak Handle

The Hado Shiosai series is an SG2 powder metal blade with an octagonal urushi oak handle.

SG2 steel is a stainless powder metal with a fine grain structure and a good blend of toughness.  It makes for easy sharpening, especially for a stainless steel at this hardness, and posseses great edge life.

HADO is based in Sakai, Japan, launched in 2019 by Fukui & Co. Ltd. The brand was influenced by Tadataka Maruyama, a former sales and warehouse manager at Fukui & Co., whose passion for craftsmanship led him to train for three years with master sharpeners in Sakai. With the support of company president Motonari Fukui, HADO was created to foster Maruyama’s journey and uphold Sakai’s sharpening traditions. Though Maruyama has since pursued his own independent work, his influence remains central to HADO’s approach.

HADO works with some of Sakai’s most respected blacksmiths—including Yoshikazu Tanaka and Satoshi Nakagawa—who forge blades from a number of premium steels as well as high-grade pre-laminated stock. These are then sharpened and finished by HADO’s in-house team, ensuring exceptional craftsmanship in consistent geometry and refined edges.
