Ideal for: Chopping, slicing, and disjointing.
Useful on food types: Small to large proteins including whole fish, poultry, beef and pork.
Deba Japanese kitchen knives are ideal professional thick and heavy single bevel blades designed to breakdown fish, poultry or meat. The Deba knife is meant for butchery with a thick blade, in particular the heel, to help cut through joints, tendons and cartilage.
I used this knife with an experienced fish shop owner.
Overall, this knife is great. It is easy to cut thick bones off. However, I need to practice how to cut fishes because this knife is thick and heavy so I can not feel bones compared to a thin flexible knife. Having this knife does not mean you can fillet fishes easily. Anyway, if you want to fillet whole fishes, you should buy this.
