I have been storing 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 is Hitachi Metals SLD, and the base steel is 73-layer nickel Damascus, resulting in a very beautiful Damascus pattern on the surface. It has outstanding sharpness and edge retention. The handle uses a walnut octagonal pattern. [Santoku Knife] ■ Blade length: 165mm ■ Material: SLD steel ■ Handle: Walnut octagonal pattern ■ Blade: Double-edged (right-handed/left-handed) *Please note ・Although it is a rust-resistant material, please remove dirt and thoroughly wipe off moisture after using the knife. Leaving moisture or dirt on the knife can cause rust. ・Do not use in dishwashers or dish dryers. ・Do not use on frozen foods, corn, pumpkin, dried mochi, or hard ingredients such as bones and shells, as this may cause chipping, cracking, or breaking of the blade. Thank you for viewing.
