Glestain 9.4-inch (240mm) Deba

For fabricating large, powerful fish such as tuna, swordfish and large salmon, the 240mm deba has the weight and length the job demands. It removes heads and collars, splits frames and takes fillets from fish too large for a smaller deba.

The blade has a smooth W Series face and the clean look of a classic deba, in stainless steel that resists rust at the fish station. Its edge is ground close to a single bevel, with only a small back bevel, so it cuts with the precision of a traditional deba.

At almost double the carbon content of standard German stainless steel, this knife is over 20% lighter than carbon steel debas of the same size, significantly reducing fatigue during long sessions. A 240mm deba is a professional tool for fishmongers, sushi kitchens and anglers who land large fish.


Choosing a Deba Size

The Glestain deba also comes as a 160mm Deba and a 200mm Deba. For filleting flatfish and portioning, pair it with a flexible fillet knife or a sujihiki. Our guide to kitchen knife shapes explains the deba.

    Sharpening a Glestain Edge

    One face of a Glestain blade drops almost straight from the spine, and the other tapers to the edge, so the two sides are sharpened at different angles. Work the primary face (the right side on this knife) at about 16 to 18 degrees until a burr forms along the full edge, then remove the burr from the left side at about 22 degrees with a few light passes. Sharpen on whetstones; a pull-through or electric sharpener grinds both sides alike and alters the geometry. Our article on sharpening Glestain and Masahiro knives explains the method in detail, and our video on sharpening compound bevel knives shows it on the stone.


    Care

    • Wash by hand with warm water and mild soap, then dry the knife at once. Do not put it in a dishwasher.
    • Acuto 440 resists stains but is not immune to them; do not leave the blade wet or soaking.
    • Cut on wood or plastic boards, and keep the edge away from frozen food, hard shells and heavy bone.
    • Hone between sharpenings with the Glestain hexagonal ceramic honing rod, and store the knife in a guard, a block or a case.
