I have kept this in storage for a long time. As far as I can tell 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 understand that returns and exchanges are not accepted, so please purchase only if you agree to this.* The core is Yasugi Steel Blue Paper No. 2, a knife with a small amount of chromium (less than 0.5%) and tungsten (1-1.5%). It has higher hardness while also being tough, and the steel has consistently high wear resistance. The base steel is SUS406, a three-layer construction. The sides are sandwiched with stainless steel, making it rust-resistant and easy to use at home.
