There are a few considerations every angler should consider before choosing a saltwater fishing knife. In this section, we take a closer look at each of these factors.
Generally, fixed knives are best suited to hard tasks while folding knives are ideal for light-duty applications. Fixed blades are more durable and don’t break easily. On the other hand, folding blades have more points of weakness and are more susceptible to corrosion.
The size of the blade is always a significant factor to consider, regardless of the intended purpose. And while bigger is always better, a blade that’s too long may compromise your ability to complete finer tasks efficiently. On the other hand, a short blade doesn’t perform well when it comes to rugged applications like chopping or batoning. We recommend choosing a knife that’s at least 3” long and at most 10” long.
Full Tang refers to knives whose blade and handle are made from a single piece of metal.
Full tang blades are more robust than push tang, half tang, and rat-tail tangs. This is because partial tang blades tend to loosen with continued exposure to demanding tasks.
Full tang knives are usually wrapped with cordage, wood, hardened plastic or other material to ensure a comfortable grip.
Stainless steel is the best material choice because it is leaps ahead of other materials regarding durability and corrosion resistance.
Titanium is also a good choice as it is super durable and resistant to rusting. While lightweight and strong, aluminum doesn't stand up well to prolonged moisture exposure.
A good, solid grip is an essential factor to consider when shopping for a saltwater fishing knife. The last thing you need is a knife that keeps sliding through your fingers every time you try to cut. This is not only inefficient but also increases the risk of accidental cuts.
Most companies have a reputation for patented handle designs that ensure comfort, efficiency, and optimal safety. Look for handles with grooves or rubber coating.
