Ryusen Blazen Ryu Wa Petty 135mm

About the Shape - This is the knife for smaller jobs that are done on a cutting board. Perfect for slicing shallots, cutting herbs, and boning smaller proteins. Additionally, Petty knives are an indispensable tool for those who feel uncomfortable wielding a larger chef knife.

About Ryusen Blazen Ryu - Ryusen Hamono was founded in 1948 as a knife sharpening company. They worked with companies like Takefu Special Steel as early as the 1970s to develop high-quality knives made with stainless steel, at a time when most other knife makers were struggling to produce decent stainless steel knives. Now, they have expanded their collection of knives not only having sharpness and longevity in mind but with a sleek modern design.

The Blazen Ryu series elevates traditional Japanese design with tasteful modern touches. The blade is forged from super-hard R2 stainless steel, known for superior edge-retention and laser-sharpness. The Canadian-walnut octagon handle is tapered toward the blade, creating the ultimate ergonomic grip.
