Matsubara HAP40

HAP40 is one of the most impressive steels in a serious knife collection - a semi-stainless powdered high-speed steel that holds an edge for an exceptionally long time and responds beautifully to stropping. Matsubara produces a select few knives in this steel, and the combination of traditional Nagasaki blacksmithing craft with modern powder metallurgy makes for a genuinely compelling knife.
