In order to prepare sashimi, this knife is ideal. Even beginners can handle it quickly. The technique you should try out on Youtube and then practice the fillet. One zersäbelt with this knife not the fat layers in the salmon fillet. Once before, once cut back and have a piece of thin salmon for sashimi or sushi.
My tip: Place the fillet laughter for a short time in the freezer, so it is not too soft for cutting.
