Hatsukokoro Komorebi Blue 2 Hon-Kasumi

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

Komorebi(木漏れ日) Blue 2 Hon-Kasumi line is something completely new to the market when it was first brought to the market in 2022. The name in Japanese describes the sunlight that streams through the trees, which is a very clam and peaceful natural scene. And the reason behind this name is the beautiful natural stone finish that the blade been put through, complemented by the organic cladding line across the edge.

Natural stone finish. Rarely a Japanese kitchen knife is finished on a natural stone. Shigefusa probably being the only one that I could name on top of my head. Doing it this way significantly increases the overall level of the F&F of the knife, and is very unique given that Shigs can’t be easily obtained these days.

Many of the knife enthusiasts prefer the larger Sanjo / Echizen profile to the shorter Sakai profile, as a result we are offering the Komoberi in a more traditional Sanjo profile that is very tall, and the length is true edge length rather than tip to machi length. The heel is also quite significant along with a pronounced distal taper, translating into a very thin thickness behind the edge.

These features really make the Komorebi line stand out, and in some sense a one-of-a-kind line, yet the presentation of these blades are done in a subtile way, while in my opinion aligns with the poetic Japanese aesthetic very well.

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.
