The Mujun S52-J deba 16.5 cm is a heavy Japanese kitchen knife. The Deba was originally designed for filleting and preparing meat and fish. The blade is thicker than that of an average kitchen knife. This allows you to easily apply more pressure to easily cut through small bones, ligaments and tendons without damaging the knife's edge. This knife is sharpened on one side while the other side is hollowed out. This ensures that meat or fish does not stick and falls off the blade easily while you are cutting.
