Spearfishing knives have one purpose – provide the last rites to your fish. But at the same time, these knives can be extremely versatile and is a helpful companion for other purposes as well. Such knives usually come with different sides for the blade and low profile design and other extras that make them quite versatile.
Now, choosing the best spearfishing knife asks for a little research before spending your money. You will have to explore a growing market with numerous options – from more or less known manufacturers. You need to assess your needs and go through others’ reviews and consideration. Here is our take on top spearfishing knives in the market.
What’s an Ideal Spearfishing Knife?
A spearfishing knife should have a very pointy tip, as you need to penetrate easily. At the same time, a bit of thickness and sturdiness are mandatory because the pointy tip might break. The side with the blade is most commonly used for cutting applications, not to mention gutting the fish. Most knives come with a serrated side as well – generally used to cut rope or line, as it is more efficient for such uses.
When it comes to extras, while not all the knives have it, a spear removal tool is just as important. This tool slides over the spear, letting you twist it out. The spear will come out within a few seconds then, with no effort whatsoever. As for the knife itself, it is supposed to be quite lightweight and super sharp. Most knives feature a straight fixed blade. You may be able to find some folding spearfishing knives as well.
You will find spearfishing knives with blades made of titanium and stainless steel. The titanium blades are resistant to rust and require minimal maintenance. The downside is they are harder to sharpen and usually cannot be made as sharp as steel. The steel knives are not only easier to sharpen, but also hold an edge well.
