SPG STRIX is a brand new specialty powdered steel. It is produced by Takefu Special Steel Company. The high hardness, along with substantially finer grain structure and carbides, set STRIX apart from more conventional powdered steels on the market. This paired with advanced forging and heat treating allows for outstanding edge retention without having to sacrifice ease of sharpenability.

Nakagawa-san's knives are characterized by excellent heat control during forging and a very thorough heat treatment. This creates knives that have superb edge formation and edge life, with good toughness. Nakagawa-san's reputation is well earned as one of a few blacksmiths in Sakai to forge Ginsanko, VG10, and STRIX stainless steels. Likewise, his carbon steels are easy to sharpen across most steel types. 

Sakai Kikumori was started in 1926 and draws on Sakai's 600 year history as the major center of traditional Japanese cutlery manufacturing. They work with a large variety of Sakai's best smiths, sharpeners and small factories to offer a wide variety of knives ranging from traditional to modern.
