All of our stainless steel blades are heat treated for optimum hardness and edge retention while maintaining the ability to be sharpened to a razor's edge. The steel used is perfect for kitchen specific tasks because of its corrosion resistance, preventing it from oxidizing with rust when it comes in contact with meat, fruits and vegetables. Each GINSU KATANA knife blade is forged. Forged knives are made up of a single bar of steel, wherein the process of compressing the steel makes it harder and stronger. 

Store your GINSU KATANA knives in a countertop knife block, divider drawers, on wall-mounted magnetic strips or in a Saya. Choose what is best depending on your preference. To clean your knives, hand wash with mild soap, rinse and towel dry. Our GINSU KATANA knives are NOT dishwasher safe. Always cut on a wood surface. Softer woods like maple and walnut provide the best surface. Avoid marble, steel, glass or ceramic material as they can dull and/or chip the blade.

We guarantee our knives against any manufacturing defects in material and construction, and to perform as advertised when properly used and maintained.
