Petty 150mm (5.9")
The Petty knife is light and thin with a bit of flex to it and is used for peeling, chopping and trimming. Not used in a hammer grip way meaning you don’t chop up and down like a chefs knife due to not having enough clearance for the knuckles. Mostly used for cutting away from the chopping board but is essential for any knife roll and home kitchen. The general size of a petty ranges from 95mm to 150mm but can go up to 180mm but this is considered to be in a slicing categories.
Ryuhyo (流氷) is the Japanese word for drift or pack ice referring to large masses of sea ice that float and drift, particularly famous in the sea off Hokkaido, Japan, where they originate from the Amur River. Kurozome (黒染め) literally means "black dying" in Japanese and refers to a traditional dyeing process, particularly popular in Kyoto, that creates a deep, long-lasting black hue for textiles like kimono, but the term is also used in knife making for a distinctive dark, etched finish on steel blades.
Developed by Takefu Special Steel, Super Gold 2 (SG2) is a premium powdered tool steel alloy specifically engineered for crafting high-quality blades. Renowned for its exceptional performance and durability, SG2 has earned its reputation as one of the most sought-after high-end powder steels in the blade-making community. With the ability to be heat-treated to an impressive hardness of up to 64 HRC (Rockwell hardness scale), SG2 blades exhibit outstanding edge retention and wear resistance. Interestingly, there is a steel known as R2, produced by Kobelco Steel, which is widely believed to be identical to SG2 in composition and properties.
