Ginsan, also sold as Silver 3, Gin-3, or Ginsan-ko, is a stainless steel from Hitachi Metals, now renamed Proterial. It has a reputation as the stainless that sharpens like carbon steel, which is why traditional Sakai makers use it in single-bevel knives for customers who do not want to fight rust.
What Ginsan steel is
It is a fine-grained stainless with enough chromium to resist rust and a carbon level tuned for a keen edge. It has no heavy carbide-forming additions, which keeps sharpening fast. Makers usually harden it to HRC 60 to 62. It is often forged with a soft iron or stainless jigane backing on single-bevel knives, the same construction used for carbon blades.
How a Ginsan knife behaves
It takes a very fine edge and sharpens quickly on water stones, with a clean burr that is easy to remove. Edge retention sits around Shirogami 2, below VG-10 and well below SG2. Toughness is reasonable. Rust resistance is good, not quite at VG-10 level, but far beyond any carbon steel. It will not build a strong patina or react with onions.
Who makes Ginsan knives
Sakai is the center of Ginsan work, largely in single-bevel shapes. Sakai Takayuki offers the Ginsan nakiri and the Ginsan yanagiba. Some Sanjo and Echizen makers offer it in double-bevel knives too. Expect roughly $120 to $350 depending on shape, length, and finish, with prices moving with the yen.
Ginsan vs Shirogami 2 and VG-10
| Steel | Type | Edge retention | Sharpening | Rust |
|---|---|---|---|---|
| Shirogami 2 | Carbon | Lower | Easiest | Rusts fast |
| Ginsan | Stainless | Lower | Easy | Resists |
| VG-10 | Stainless | Middle | Middle | Resists best |
Ginsan vs Shirogami is the common single-bevel choice. Shirogami sharpens a touch faster and gets a slightly finer edge, while Ginsan saves you the wiping and oiling. Ginsan vs VG-10 is about feel. VG-10 lasts a little longer and resists rust a little better, while Ginsan is quicker and more pleasant to sharpen. The steel guide compares all eight steels.
Who should buy Ginsan
It is ideal for home cooks who want a yanagiba, deba, or usuba but do not want carbon steel care. It also suits a nakiri for someone who sharpens on stones and wants a keen, low-fuss vegetable knife.
Maintenance
Hand wash and dry. Use a wood or soft synthetic board. Sharpen on a 1000 grit stone and finish on 4000 to 8000. Single-bevel knives need a slightly different routine, covered in our single vs double bevel guide and whetstone guide.
Downsides
Edge life is modest, so it needs regular sharpening. It is less common than VG-10, so fewer shapes and makers are available. Ginsan single-bevel knives often cost more than similar Shirogami ones, and the stainless jigane on some models makes the back harder to maintain on stones.

Frequently asked questions
Is Ginsan really stainless?
Yes. It has enough chromium to resist rust in normal kitchen use. It can show small spots if left wet for a long time, so dry it after washing.
Why is Ginsan called stainless that behaves like carbon?
It has a fine grain and sharpens quickly with a clean burr, much like Shirogami. Most stainless steels feel slower and gummier on the stones.
Is Ginsan good for a yanagiba?
It is one of the best choices for a cook who wants a traditional single-bevel knife without the rust care of carbon steel.
