The HD2 line is made from proprietary semi-stainless steel that takes on an easy patina and a keen edge. The masterfully done convex geometry allows smooth cutting performance through even the toughest of ingredients, without chipping easily. We highly recommend this line to virtually any cook who is looking to invest in a carbon-like stainless steel blade that can handle nearly all tasks. Nakiri is a versatile blade that excels in processing large amounts of vegetables and the rectangular shape is also very useful to pick up all the chopped bits!
