MAC 4-inch Aji Deba

An aji deba is the small deba, named for the horse mackerel it was made to clean. The MAC CL-40 is a 4-inch version for small fish such as mackerel, sardines, trout and smelt, and for shellfish prep.

The short, thick blade opens the belly, removes the head and fillets small fish with precise control, and its weight is enough for the thin bones of a small fish. A full-size 6.5-inch deba is better for salmon and snapper.

    Keeping the Edge

    Sharpen this knife by hand on whetstones, following the angle of the factory bevel. A pull-through sharpener or a honing rod is not suited to a heavy fish knife.


    Care

    • Wash by hand with warm, soapy water and dry the knife at once. Do not put it in a dishwasher.
    • MAC steel is stainless but not immune to spotting; do not leave the blade wet, soaking or in contact with acidic food.
    • Use it on small fish bones only; do not use it on beef or pork bone or frozen food.
    • Cut on wood or plastic boards. Keep the edge away from bone, frozen food and hard shells.
    • Warranty claims are handled by MAC directly.
