Blade Type

The Petty is a smaller utility knife, often ranging from 120-150mm. It is for fine dicing, mincing, and off-board work.

Steel Type

Japanese SG2, also known as R2 steel, is a high-end, powdered metallurgy stainless steel and one of the finest knife-making steels available in Japan. It is a favourite of many for its exceptional hardness and edge retention. Its fine, uniform grain structure enables razor-sharp edges, all the while holding an edge for much longer than Carbon steel knives, without needing to be concerned about rust appearing.

Recommended Maintenance

Store it in a dry environment using magnetic strips, knife rolls, or sayas. Avoid hitting hard or frozen objects and twisting the blade while cutting. These knives are not dishwasher safe. Clean with hot water and a soft cloth, and dry immediately after use to prevent rust spots on the high carbon steel. For more information please read the blog below.


Kei Kobayashi

After sharpening many knives for some of the top Japanese Blacksmiths, Kobayashi-San decided to create his own kitchen knives. His knife range is now among the most popular in Japan. These are true lasers, extremely thin, light, and use SG2 as the core steel.
