Japanese Chef Knife Hokiyama *Naoto Blue 1 Black Damascus Santoku 165mm

This is a “Tosa Naoto” Santoku knife, manufactured by Hokiyama Cutlery in Kochi Prefecture, Japan, a region renowned for its long tradition of Tosa cutlery craftsmanship.

The core is made from premium Aogami #1 (Blue Paper #1 / Blue #1 Steel), originally developed by Hitachi Metals (now Proterial). The reverse side of the blade is clearly stamped “Ao-Ichi Hagane” (青一鋼), indicating the use of Blue #1 Steel.

Aogami #1 is a high-carbon Japanese cutlery steel alloyed with chromium and tungsten. When properly heat-treated, it is capable of taking an exceptionally keen edge while providing excellent edge retention and wear resistance. These qualities have made Blue #1 a highly regarded steel for high-quality Japanese kitchen knives.

One of the most striking features of this knife is its beautiful multi-layer steel construction. Numerous layers flow across the lower portion of the blade, creating an organic, wave-like pattern. Each blade displays subtle variations in its layered pattern, giving every knife its own individual character. The polished layers also create a beautiful contrast with the darker finish on the upper portion of the blade.

The Santoku is one of the most versatile and widely used Japanese kitchen knife styles. Its name is commonly associated with its suitability for the “three virtues” of meat, fish, and vegetables, making it an excellent all-purpose knife for everyday preparation.

The generous blade height provides comfortable knuckle clearance, while the relatively flat cutting profile works particularly well for push-cutting, slicing, and chopping vegetables. Its well-balanced dimensions make the Santoku an approachable and highly practical choice for a wide variety of kitchen tasks.

The front of the blade bears the “Tosa Naoto Saku” (土佐直斗作) inscription and maker’s mark, while the reverse is stamped “Ao-Ichi Hagane” (青一鋼 / Blue #1 Steel).

Manufactured in Kochi Prefecture by Hokiyama Cutlery, this Santoku combines the excellent cutting characteristics of premium Blue #1 carbon steel with the distinctive beauty of multi-layer Japanese blade construction and the versatility of the traditional Santoku profile.

Made in Kochi, Japan.
