A good fishing knife is an essential tool for every angler. You will need an all-purpose knife - one you'll be carrying on your person. Plus, it's best to accompany your main knife with other specialized knives, like a filleting knife. Fishing lines are strong and designed to be unbreakable. This means they won't easily snap. So, when you need to cut your fishing line don't try and do this with a dull blade. Using a proper fishing knife can cut it clean in a snap. After the catch, you're going to need to clean the fish. To do this well, you need specialized knives. An all-purpose knife may be able to clean but don't expect clean filleting. To remove a nice clean fillet, you'll need a sharp filleting knife. Fishon stock a range of good quality rust-resistant  knives and cutters to meet your fishing needs.
