Wusthof Classic 7-Inch Fish Fillet Knife
Our favorite fillet knife is the Wusthof Classic 7-Inch Fish Fillet Knife. This knife is a great length for most medium-sized fish and has a slightly flexible blade. This flexibility allows the knife to slip easily through the body of a fish, though it can take some practice to get used to using a blade like this. Like all Wusthof knives, this one is made from a high-carbon German stainless steel that is finished with an extremely sharp edge. If you're looking for a knife to take with you on your next fishing trip, Wusthof also makes a fitted sheath that protects the knife from damage.
