Hatsukokoro Blue 2 Damascus(Tosa)

Sanmai - Soft Iron Damascus Clad Migaki Blue 2 / Aogami #2 / Carbon Hyogo, Japan

The Blue 2 Damascus line developed by Hatsukokoro is constructed with blue 2 core steel and iron Damascus, a combination that is more often found on some very high end Sakai knives. But, judging by the features of these blades, they are likely forged in Tosa region similar to many other Kurouchi carbon knives from Hatsukokoro that we are familiar with.

What is not similar to those other Kurouchi knives is, the finish that Hatsukokoro put on these knives. To reveal the fine Damascus pattern in the cladding, these knives receives a very smooth Migaki polish, it creates contrast between layers of different steels, and removes the rough scratches that are usually found on other knives from the same maker.

The profile and geometry are still in line with its close relatives, this line have a rather thick spine that tapers down, and a strong convex bevel that starts rather low on the blade, which offers strong food release but a little to thick and can created some resistance when wedging into some harder food like roots. However, the blue 2 can still offer an excellent sharpness at the edge, making the food penetration very satisfying when paired with the weight of this thick blade.

Due to the additional steps used to give this knife a clean finish, the price went up correspondingly and now I wouldn't consider this is a "budget" line. The combination of carbon core steel and iron cladding means these knives demands more attention as well. However, when all things are considered, this line is still a easy way to get this classic construction, and knives that looks similar to is would usually be priced two to three times.

Frequently asked questions

What is the difference between Blue 2 and White 2 steel?

Proterial lists 1.05 to 1.15% carbon for both steels; its Blue 2 table lists 0.20 to 0.50% chromium and 1.00 to 1.50% tungsten, while its White 2 table lists neither.

Proterial describes White 2 as a carbon steel with minimum impurities and high hardness, and Blue 2 as an alloy steel with tungsten and chromium to improve heat-treatment properties and wear resistance, with a hardening hardness of over 60 HRC for both. In its Japanese materials, Proterial calls its Aogami (青紙) steels high-carbon steel (高炭素鋼). Neither steel is close to the JSSA's 10.5% minimum for stainless.
