This Sakon Ginga series of knives feature a nashiji finish, ombré lacquer handles and semi-stainless ginsan steel. While not as corrosion resistant as some other stainless steels, you would really have to push your luck to rust these knives, though we still recommend with all knives to keep them wiped down, dry and clean at all times. The benefit of ginsan being a semi-stainless steel is that it is considerably easier to sharpen than other traditional stainless steels and will more readily benefit from higher grit stones.
These knives are relatively thin at the spine and quite thin behind the edge. This gives them a great cutting feel, but we don't find these knives to be particularly delicate, which makes them a great knife to start out your collection with, or for a high volume professional that needs a steel that is both corrosion resistant, and easy to sharpen.
