Product Description : Whether you’re cutting line or fileting a fresh catch, a good fishing knife is a necessity for hobbyists and avid fishers alike. Our Traditional® 5″ Fish Knife is designed specifically to fit the needs of fishers of all types. This knife features a 5″ carbon steel blade that is designed for ideal flexibility and durability. The blade may develop a black patina over the course of use, but this is completely normal. To prevent rusting, try coating the blade in mineral oil. (#10411)
