This is a Zwilling Twin Cermax MD67 130mm petty knife. The blade is sharp and has no issues, but there are fine scratches and small, dot-like areas of oxidation. The core material is particularly hard, so the knife is incredibly sharp, but some small black spots are visible. I believe these could be removed with polishing, but please check the images. Although there are some scratches, it has only been used a few times and sharpened a few times. There are no chips in the blade, and there is almost no wear. Please consider this item.
