Another new line we recently added to our canon of products from Tsunehisa is this range of AUS-8 based knives. AUS-8 is a lower-carbon version of AUS-10 and is similar to 440C or D2 steel. It is made in Japan by the Aichi Steel Company. You will occasionally see two AUS-8 steels being used by knife makers: plain AUS-8 and AUS-8A. They are identical steels but are processed differently after heat treatment. Plain 8 receives a cryogenic soak whereas 8A is annealed after being heat treated. This slow cool down process will alter the hardness by a few Rockwell points. The result is a very high level of corrosion resistance coupled with great hardness, toughness, and harden-ability, high levels of wear and abrasion resistance.
This 180mm nakiri
features a good looking tsuchime (hammered) finish. These dimples are formed by hammer blows and as well as adding to the fine aesthetic, result in a knife that easily sheds ingredients from its blade face.
The blade is attached to a stainless bolster in a full tang set up. The nicely finished handle completes a picture that is attractive and exceedingly functional especially given its very keen price.
