4. What Is the Best Size Deba Knife for Your Kitchen?

The answer depends on the type of cooking you do and the size of the fish or meat you prepare. From our hands-on testing, the 165–180 mm deba knife is the sweet spot for most home cooks and even many professionals. It’s compact enough to control, yet powerful enough to break down medium-sized fish with ease.

Smaller 150 mm blades are great for sardines or mackerel, but they can feel limiting if you handle larger fish. On the other end, 210 mm and above are better suited for salmon or tuna, offering the extra length you need for clean, confident cuts. 

For daily use, we consistently recommend the 180 mm size as the most versatile choice. It strikes the perfect balance between precision and strength.

For everyday cooking, the 180 mm size is our top pick for versatility

Deba Knife FAQs

If you cook often, sharpening every 2–3 months keeps your deba performing at its best. For lighter use, 2–3 times a year is enough. Between sharpenings, use a honing rod or whetstone touch-ups to maintain the edge.

For salmon, a 210 mm deba knife is ideal. It gives you the extra length and weight needed to cut through larger fillets cleanly without losing control.

The most versatile choice is 180 mm. It works well for everyday fish prep, offering a balance of control and cutting power that suits both home cooks and professionals.
