The Legend of Japanese Carbon Steel
The PM8M Zhen Series is crafted for the culinary purist. At its heart lies the legendary Aogami #2 (Blue Paper Steel) from Hitachi Metals, Japan. Revered by sushi chefs and knife enthusiasts worldwide, this high-carbon steel offers a level of sharpness and "cutting feel" that stainless steels simply cannot match.
Why Choose the PM8M Blue Steel Series?
- Aogami #2 Core (62-64 HRC): This series features a core of Japanese Blue Steel No. 2. Infused with tungsten and chromium, it achieves a high hardness of 62-64 HRC. This allows for an ultra-thin, razor-sharp edge that glides through ingredients with zero resistance.
- Superior Sharpening Feel: One of the greatest benefits of Aogami #2 is how easily it takes a new edge. Unlike hard stainless steels which can feel "glassy" on a whetstone, Blue Steel offers excellent tactile feedback, making it a joy to sharpen and maintain.
- Stainless Cladding (San Mai): To make maintenance easier, the reactive high-carbon core is clad in layers of softer stainless steel. This "San Mai" construction protects the majority of the blade from rust, exposing only the cutting edge to the elements.
- Figured Maple Wood Handle: The handle is crafted from premium North American Maple Wood, prized for its durability and beautiful, wavy grain. It is shaped into an octagonal Wa-style design and finished with a buffalo horn bolster for perfect balance.
