Japanese White Steel No.2 Knives

White Steel No. 2, also known as Shirogami or “White Paper,” is used to create many of the traditional Japanese knives that are available here at Hasu-Seizo. It has long been considered to be the closest comparison to the traditional tama-hagane steel that had been utilized in Japan for centuries, and it is known for its incredible sharpness due to its purity and high carbon content.

It has long been considered to be the closest comparison to the traditional tama-hagane steel that had been utilized in Japan for centuries, and it is known for its incredible sharpness due to its purity and high carbon content.

The Composition of White Steel Number 2

White Steel No. 2 is essentially identical to White Steel 1, but it contains slightly less carbon, which makes it less brittle and less prone to chipping. The downside of having less carbon is that it does not retain its edge for as long. That said, White Steel 2 knives still rank among the sharpest knives, only outmatched by White Steel 1.

The Difference Between White Steel and Other High Carbon Steels

White Steel and other high carbon steels such as Blue Steel 2 have similar structures in terms of how much carbon they contain. But several things set them apart. For starters, kitchen knives made out of White Steel Number 2 will typically be easier to sharpen than those that contain additional elements like molybdenum, tungsten, and other metals. These additions make knives more durable than knives with White Steel 2 and less prone to corrosion. The generally have better edge retention as well, but the tradeoff is they are harder to sharpen and do not get as sharp.

Frequently Asked Questions

All the alloys of real Japanese knives are high-quality but each comes with its own tradeoffs. Blue Steel 2 will hold up better and be less likely to chip, and it won’t need to be sharpened as often. But if you are looking for incredible sharpness with good durability and ease of sharpening, White Steel 2 is an excellent choice.

White Steel Number 1 is very similar to White Steel Number 2 with one of the only big differences being that it contains more carbon. This allows White Steel 1 to be sharper, but it also gives it less toughness overall and becomes more brittle.
