I have stored this for a long time. As far as I can see with the untrained eye, there are no noticeable scratches or rust, but there may be some if you look closely. Please refer to the photos. *Please purchase only if you understand that returns and exchanges are not accepted. The core steel uses V Gold No. 10, a high-grade cutlery steel, making it highly resistant to rust and very hard. Salt bath heat treatment further enhances the sharpness. The sides use SUS410 stainless steel, which is rust-resistant, hygienic, and easy to sharpen. The beautiful ripple pattern is created through special forging, and DP treatment is applied to the joint. The handle is made of laminated reinforced wood black plywood. This is a wonderful knife that has the three most important qualities for a kitchen knife: sharpness, long-lasting sharpness, and ease of sharpening. It is a very easy-to-use knife, making it a recommended addition to any home.
