Genuine blade attachment, rust-resistant. ◆ Product Details: A new Damascus knife "Yoryu" series created with the theme of the sea. Using 440C, 440B, and our proprietary steel MKV10, craftsmen repeatedly fold and forge the steel, and acid etching is applied to the 105-layer laminated blade. The unique pattern, different for each knife, is beautiful and achieves excellent sharpness along with visual impact. After heat treatment, it is adjusted to HRC63, and then to HRC61 by tempering, achieving both sharpness and toughness. It has a slightly heavier feel than a knife made of MKV10 single steel, and you can enjoy a well-balanced feel. The stainless steel material also provides excellent rust resistance. Despite the complex manufacturing process, we keep the price down. It is priced several tens of thousands of yen lower than commercially available Damascus knives of the same quality, making it a cost-effective choice. 【Please Note】When sharpening, slightly raise the blade tip and polish only the cutting edge. Avoiding the patterned areas will preserve the beauty. Even if scratches occur, the pattern will reappear by soaking in vinegar or citric acid for 10-15 minutes.
