Exotic: Yoshikazu Ikeda White 1 Mizu-Honyaki Sakimaru Takohiki 270mm, Fujinami Hamon Nenox Style Ebony Handle

Among the many beautiful Honyaki knives produced in Sakai, the works of Yoshikazu Ikeda (池田美和) have always held a special place. This exceptional piece, produced under the Sakai Hokushin (堺北辰) brand, brings together Ikeda's mastery of traditional Honyaki forging and the remarkable sharpening skills of Nori Igarashi (五十嵐 宣). What makes this knife particularly fascinating is its elaborate Fujisan hamon, accompanied by two different moon motifs on opposite sides of the blade, all presented against a stunning full mirror polish. It is a beautiful example of how traditional Japanese knifemaking can extend far beyond the practical requirements of a kitchen knife.

Forged from Shirogami #1 (White 1) carbon steel, the blade uses the traditional Mizu Honyaki (water-quenched) process, one of the most demanding techniques in Japanese knifemaking. Unlike conventional Sanmai knives, Honyaki blades are formed from a single piece of steel and differentially hardened to achieve a very hard cutting edge while leaving the spine comparatively softer. Water quenching introduces additional challenges due to its rapid cooling rate and the significant risk of warping or cracking during heat treatment. White 1, with its high carbon content and relatively simple composition, is capable of achieving exceptional sharpness and hardness, but also requires considerable skill to heat treat successfully. It is this combination of difficult materials and demanding techniques that makes a water-quenched White 1 Honyaki such a special achievement.

The most captivating aspect of this blade is undoubtedly its Fujisan (富士山, Mount Fuji) hamon. Rather than a simple straight or wavy temper line, the hamon rises and falls to create the silhouette of Mount Fuji, beautifully revealed through the mirror-polished steel. Adding another layer of artistry, the hira side features a delicate Mikazuki (三日月, crescent moon), while the Ura side displays a Mangetsu (満月, full moon). The two different phases of the moon give each side of the knife its own character, creating a complete landscape-inspired composition when viewed together. Both sides have been brought to a full mirror finish, producing an extraordinary contrast between the reflective surface, the subtle hamon and the carefully placed moon motifs.

The sharpening was entrusted to Nori Igarashi, a highly accomplished Sakai sharpener associated with Yamawaki Hamono. Working on a Honyaki blade requires a different level of skill compared with conventional laminated knives, as the hard monosteel construction offers very little forgiveness during grinding and sharpening. Achieving a clean geometry while preserving the beautifully finished surfaces is a demanding process, particularly when both sides are mirror polished. The resulting blade represents not only the blacksmith's achievement in forging and heat treatment, but also the equally important contribution of the sharpener in bringing the knife to its final form.

To complete this remarkable piece, we at K&S have paired the blade with a Nenox-style ebony handle, adding a touch of contemporary character to the otherwise very traditional Japanese craftsmanship. The dark ebony provides an elegant contrast against the highly reflective blade, while the distinctive handle design gives the knife a personality of its own. I particularly like how this combination brings together two rather different design philosophies: the traditional Japanese approach to forging and finishing, and the more modern aesthetics associated with premium Nenox knives.

This is certainly a knife that deserves careful ownership. White 1 carbon steel is reactive, and the full mirror finish will readily develop marks or patina through regular use. Honyaki construction also requires greater care when cutting and sharpening, making it less forgiving than conventional laminated knives. However, for serious collectors and enthusiasts, the appeal goes well beyond practical cutting performance. The combination of Yoshikazu Ikeda's water-quenched forging, Nori Igarashi's sharpening, the elaborate Fujisan hamon with its contrasting crescent and full moon motifs, and our specially selected ebony handle makes this a particularly memorable piece of Japanese craftsmanship.
