The most useful tool on the Gerber is probably the pliers as they are great for everything from tying knots to crimping barbs on hooks and lots more. The blade on the Gerber is also excellent and you can definitely gut fish with it and prepare a camp dinner, but it is too small for fileting. 

Built from stainless steel, the blade is tough and it handles saltwater well but you will need to rinse it after. The blade is sharp too, easy to sharpen, and holds its edge well. It also locks in place so you can do some heavy cutting when you need to.

The Victorinox Fisherman Swiss Army Knife is another fishing multi-tool with 18 handy tools that makes life easier out on the water, but it doesn’t have any pliers which is a shame. 

The Victorinox Fisherman Swiss Army Knife does come with two blades though along with a descaler and a hook disgorger too so it does have some great fish-specific tools on it. 

The fishing knives on this multi-tool come in two sizes, one large and one small meaning you have one for intricate tasks and another for heavier work too. They are super sharp, great to use, hold their edge, and are easy to sharpen.

The annoying thing about this fishing multi-tool is that the blades aren’t very long.

Fishing Knife Safety

I have had a few instances where without my fishing knife, life wouldn’t have been so peachy. I got a line wrapped around my thumb with a sailfish attached to the other end, hooked by a Rapala lure that had a tuna attached to the other treble hook, and the list goes on. 

If I hadn’t had a fishing knife in these situations, my hands wouldn’t be the same, and therefore owning the best fishing knife is a matter of safety as well as being a handy fishing tool. 

Being a professional fishing guide requires me to own the best knives, not only for my own use but for the anglers that I teach also.

Fishing Knife Essential Tips

  • Always ensure that you keep your knife handle dry and clean.
  • Always dry your hands before you start to use the knife.
  • After using the knife wipe the knife down with a clean dry cloth.
  • When filleting always use a non-slip cutting board.
  • Rinse down and dry your hands, knife, and cutting board after use.
  • Always keep the blade sharp to avoid having to use extra force when cutting. 
  • Use a glove while cutting. (if possible)
  • Return the knife to the sheath once finished using it.
  • Always pick up a knife using the handle.
  • Never let a young child use your knife.

Law When Buying And Using A Fishing Knife

Knife legislation is different across each country around the world, with various restrictions. Fishing knives have no specific regulations and are considered a blade. Always check your country’s regulations, and be aware they may change from time to time.

In the United States carrying and buying a knife is under federal laws but also regulated differently at local and state levels. Therefore, when using a knife in a different state may be against the law. Always check the laws carefully in the area where you intend to go fishing in.

Why Use A Knife For Fishing?

Spyderco has a full range of fishing knives but the Salt 2 is the best allrounder

Taking a knife when going fishing has multiple uses for every type of angler. Some are critical and other tasks are just for convenience. Here are the main reasons for carrying a knife when you go off on a fishing trip:

Bait Preparation

When prepping bait there is no other tool that is in the fisherman’s toolbox which can do the job as efficiently and as fast. Bait preparation is key for predator fishing, both in rivers and saltwater. The knife can allow you to fillet different sizes and shapes very cleanly, making the bait presentation that much more appealing to the fish.

Cutting Line

Most anglers will use scissors when cutting fishing lines of smaller sizes, however when saltwater fishing a knife makes the job much easier. A heavy-duty line will blunt small scissors, but a sharp knife can slice through the line fast. If in emergency situations the knife is faster to use and the line can be further away from you when you cut it.

Keeping Your Fish To Take Home

Using a knife is the quickest and easiest way of slaughtering your allowable limit of fish to take home. The sharp blade will allow you to remove the insides that would normally be discarded such as the guts and fins. If you do need to kill the fish with a knock to its head then the handle of your knife will do the job perfectly. 

Cleaning and Filleting Your Catch

Once your fish are slaughtered, then the knife can be used to clean and fillet the fish perfectly and then put the fish in clean water or in an ice bucket or your favorite cooler box. You can check out my article on the best coolers here! Or my in-depth review on the Frabill Magnum Bait Station here!

Campfires And Cooking On Long Fishing Trips

Certain anglers combine their fishing trips with going camping and cooking – especially those that do a lot of night fishing or longer 2 or 3 days trips. This is where a good fishing knife can be essential for doing all your prep work for these tasks.
