How to Use a Deba Knife: Techniques for Using a Deba Knife
Filleting Fish
Successfully filleting fish with a Deba knife requires precision and skill, focusing on making accurate cuts along the spine and bones. Begin by placing the fish on a stable cutting board and ensuring it is clean and descaled. Use the tip of the Deba knife to make an incision just behind the gills, slicing down toward the backbone. With a gentle but firm hand, slide the blade along the spine, guiding it with the natural contours of the fish.

The thick spine of the Deba knife plays a critical role here, providing stability and allowing the blade to cut through the bones without bending. It is important to maintain a steady hand to ensure clean cuts and minimal waste. Once the fillet is separated, gently use the knife to remove the skin by slipping the blade just under the skin at the tail end and peeling it back with minimal pressure, ensuring the maximum yield of meat.
Cutting Through Poultry Bones
Safety and precision are paramount when cutting through small poultry bones with a Deba knife, such as chicken wings or drumsticks. Position the bone near the blade’s thickest part, applying gentle pressure to allow the knife’s weight to do the work.
