Wakui Polished Shirogami #2 Knives: A Sanjo Blacksmith's Experimental Kitchen Knife

Introduction

Some knives arrive with a backstory that is just as interesting as the blade itself, and Wakui knives are a perfect example. Made by Toshihiro Wakui, a solo blacksmith working in Sanjo City, the home of Japanese knife making, these knives are relatively rare and sought after by collectors. His polished Shirogami #2 line pairs stainless cladding with a carbon steel core, offering serious performance with more forgiving care requirements than a full carbon knife.

If you have been curious about carbon steel but worried about maintenance, this is exactly the kind of knife worth a closer look.

What Makes Wakui Knives Different

Wakui knives are primarily stainless cladding over a carbon core. That means the edge is carbon steel, so it can take on a patina or develop light rust if neglected, but the stainless outer layer protects much of the blade. For anyone just getting into carbon steel, or for a home sharpener who wants excellent performance with a bit less babysitting, this construction makes a lot of sense.

The polished line uses Shirogami #2 steel with a very shiny polish, often called polished White #2. They deliver phenomenal performance with less upkeep than a full carbon knife. The finish itself is striking: highly polished faces with a slightly matte texture approaching the edge, which then becomes crazy shiny right at the cutting edge. That unusual matte-meets-mirror polish is a byproduct of Wakui’s constant experimentation, and it gives the knives a look you will not find from many other makers.

From Crowbars to Kitchen Knives

Wakui’s path into knife making is unusual. His family had made crowbars for three generations, and that work made him an extremely skilled metalworker. As demand for crowbars in Japanese construction steadily declined, he faced a choice: how to earn a living while preserving his family’s craft. His answer was kitchen knives.

With little experience in knife making, he took an apprenticeship at Yoshikane Hamono, where he met his friend and mentor Kazuomi Yamamoto. For four years he worked a full shift in his own factory making crowbars, then went to work another full shift at Yoshikane, learning sharpening, forging, heat treating, and polishing. That grueling schedule shaped the maker he is today. He now makes kitchen knives full-time in a brand new workshop in Sanjo, designed specifically around knife production, just a few blocks away from fellow blacksmith Masashi.

Cutting Performance and Geometry

In use, the polished Shirogami #2 knives feel genuinely distinctive. There is a subtle convexity to the grind, so food releases and falls away from the blade rather than sticking. Even though it is technically a flat-ground knife, it does not feel flat in the way very flat knives do. Dense vegetables like carrots glide through cleanly with almost no sticking.

That convexity also changes how the knife feels in hand. It reads as a bit more robust, a workhorse with a sense of security behind the edge, while still delivering the crazy sharpness you expect from a Japanese knife. Wakui has deliberately moved away from the very flat geometry associated with Yoshikane, experimenting until he found a feel that is unmistakably his own. The result has been described as a hybrid: smooth and rugged, a workhorse-laser-beam combination that glides through food while feeling sturdy and confident.

If you pick one up and like the weight of it, the performance tends to follow. It is thicker than ultra-thin laser-style knives, yet even devoted fans of thin knives come away impressed by how smoothly it cuts.

Should You Buy a Wakui Knife?

Wakui is an experimentalist. He wants to keep trying new steels, new techniques, and new finishes, and he has moved almost entirely away from crowbar production to focus on perfecting kitchen knives. For anyone who has wanted one of his blades, this is good news: his knives should become more regularly available, which matters because they have historically been fairly hard to find.

Choose one if you want a stainless-clad carbon knife with real edge performance, an unmistakable polish, and geometry with genuine character. It suits home cooks stepping into carbon steel, sharpening enthusiasts, and anyone drawn to knives with a story behind them. This is a very Sanjo knife, in the best sense of that phrase.

Conclusion

Wakui’s polished Shirogami #2 knives combine rare craftsmanship, a distinctive matte-and-mirror polish, and geometry tuned through years of hands-on experimentation. The stainless cladding makes the carbon core easier to live with, while the subtle convex grind delivers impressive food release and a robust yet razor-sharp feel. If you have been waiting to try one of these hard-to-find blades, now is a good moment.
