How to Choose the Best Fishing Knife – What to Look Out For
If it’s your first time purchasing a fishing knife, perhaps you’re looking for a gift, or you just need a refresher to know what’s out there – check out the tips and advice in the buyer’s guide, below.
What is a Fishing Knife?
As simple as it may seem, this is actually a worthwhile question, because fishing knives come in all shapes and sizes.
So, it’s important to identify each, and what they’re used for, so you make the correct purchase when you’re ready to do so.
Some of these knives are designed with a long, thin, razor-sharp, flexible blade. More commonly known as a filleting knife, they’re used for cleaning up and deboning.
You can find such knives both in an angler’s tackle box and in the kitchen knife block at home.
Some fishing knives have a waved edge that isn’t razor-sharp. They’re also used for cleaning up a fish, with a particular emphasis on descaling.
Bait fishing knives are designed to prepare chum and bait for use when fishing. They will have a sharp serrated edge, and often feature a cut hook for snipping line.
Finally, multi-purpose knives have been included in the review, which are useful for a variety of outdoor activities, such as hunting, camping, survival, and, of course, fishing.
They typically feature a slightly thicker blade for added durability to face all the challenges you ask of them, and a drop point for more control when slicing.
Many good fishing knives often feature a flat grind blade, which will hold a razor edge without the need to sharpen regularly. However, flat grind blades are not as durable as other blade types.
The type you choose will depend on what you need the knife for, where you’re using it, and what kind of fish you’re using it on.
Fixed or Folding?
Again, this will come down to personal preference – as well as the who, what, why, where, and when of fishing knife use.
Folding knives are preferable if you need to transport the tool, or if you’re short on space. They can fit just about anywhere and are really handy to keep around.
However, their compact size isn’t practical if you’re tackling larger fish, or if you need a longer blade for a particular task.
And regardless of the quality, a foldable knife is just never going to be as strong as a quality fixed blade in the same class.
Of course, the inevitable trade-off is that knives with fixed blades can offer practical length, but they don’t travel as well.
Still, a good fixed blade fishing knife should provide a full-length tang for balance and improved control, pose no danger of folding or shutting during use, and will likely be more durable overall.
I highly recommend getting both versions just to keep all bases covered – and good pocket knives are always useful in arm’s reach.
Blade Type and Length
The type and style of the blade is very important for choosing the right fishing knife for your needs.
For filleting knives, they need to be a razor-sharp, flexible blade; with a curved, tapered edge that will help in cleaning the fish and slicing through skin and bone.
For bait knives, you should be looking for blades with sharp, serrated edges and the inclusion of a cutting hook.
Straight edge blades will be more practical for cleaner cuts – such as when you’re filleting your catch for the table.
How long you need the blade to be will depend on what you’re using it for. The larger the fish – the longer it will need to be.
Stainless steel blades are practical and popular, but carbon fiber options are also available, and are typically much lighter, and more suitable for withstanding corrosion in harsh environments.
And you need to decide if you want a fixed blade knife, or a folding one. The former has a tendency to be stronger, but isn’t as practical when it comes to portability/storage.
A folding knife, on the other hand, often has limits when it comes to strength and durability – particularly at the fold point. But they come into their own for slipping in a pocket, or a quality fishing backpack.
When it comes to fishing knives, aside from the blade, the single most important part of the tool is the grip.
Even if you’re not angling in wet conditions, handling slippery, slimy fish is a challenge, and the last thing you need is a knife that’s going to skid out of your grasp.
It’s happened to the best of us.
If you’re using it in the field, look for knives that have an ergonomic, rubberized grip. Some even come with trigger-style molds where you can better position your fingers for additional stability and control.
The very best knives will have safe, practical grips – and which should be obvious, if you’re just looking at it in a picture.
A true test of the quality of a good fishing knife is how well it’s going to stand up to the elements. For this, you’ll need something that is rugged, tough, and durable.
Most knives will be able to handle freshwater with little issue, but it’s how a blade does in saltwater conditions that you should pay attention to.
If you’re fishing saltwater, look for a knife that has been treated with anti-corrosion coatings or finishes, to improve its longevity and ward off the rust.
Take a look at the blade material, as well as what the rest of the knife is made from. This will give you a firm indication of how long it’s going to last, and the conditions it’s capable of lasting in!
As mentioned above, folding pocket knives make the most sense if you need something that’s super portable.
But you might want to transport larger, fixed blades, so they need to come with some kind of carrying solution to make this easier.
Look out for durable, strong sheaths that will keep both you and the blade protected when it’s not in use.
Sheaths that are designed not to hold water are preferable, to minimize the risk of rust and your blade sitting in the damp.
Lanyard holes are always useful, as are pouches with belt loops for attaching to your waist and keeping them close to hand.
I would recommend spending a bit more when it comes to buying a fishing knife, as with these kinds of products, you will really notice the difference.
A $100 blade is going to be light years ahead of a $20 option in the same class.
Always go for the best your budget allows, and suit your choice to what you need it for and how often you’re going to be using it.
What is the best fishing knife?
It depends on what you’re using it for. The best fillet knife for fishing might not also be the best bait knife out there.
And the best fishing knife for me might be different to the best one for you – the answer is going to be subjective.
Any of the knives in this review could win the title – it’s up to you to find out which one!
