The key to a successful fish cutting operation is the correct choice of knife. It will make even the most awkward movements skillful. Ideally, the knife should be long and the blade flexible and very sharp. When looking for a knife, you may come across the ones with dimples. Don't be alarmed, this is what we need. These dimples prevent the fish from sticking to the knife. Thanks to the dimples, small pockets of air are formed, and our thin and delicate pieces of fish are saved.
