Buying Guide

Quality of the Blade

The most important aspect of a knife is its blade as it will determine whether the knife is sharp enough to cut clean pieces. You might also use your saltwater knife to cut the line when you are out there fishing, so it is important to have a sharp blade that cuts through everything smoothly. The blade should not only be sharp but also corrosion resistant so that it does not get rusted when it comes in contact with freshwater or salt water. Most knives used for saltwater fishing are made with stainless steel as it does not corrode easily. So, make sure that you check the material of the blade before investing in a saltwater knife.

The flexibility of the blade is another crucial factor as you are deciding which saltwater knife to purchase. The knife should be flexible so that you can easily cut through the organs and bones. Depending upon the size of the fish you can go for a long or a short blade. Long and thin blades are more flexible than the short ones.

Handle Grip

The handle of your saltwater knife should be easy to grip as you are slicing your fish. Also, when you are out there fishing you might hold the handle with wet hand and if it accidentally slips out of your hand it might cause an injury. So, choose a grip that is made of non-slip material such as rubber or wood. Sometimes plastic handles are also sturdy and might provide an excellent grip.

Sharpener

When purchasing the knife, it is important to consider if it is sharp and handy. A sharp blade ensures that you get a cleaner cut every time. But with prolonged usage the knife tends to become dull and difficult to use. So, when you are looking out for a knife you should check if it is accompanied by a sharpener as you can sharpen it as soon as the edges get dull. This will prolong its usage and ensure that the blade remains in its natural condition.

Cost

Cost is another crucial factor when selecting the knife that best suits your needs. Saltwater provides a harsh environment to the knife and it can easily become dull and rusted. Though there are many inexpensive knives available online, you shouldn’t mind spending a few bucks extra to get one that is made of high-grade stainless steel so that it is easy to maintain.

Frequently Asked Questions (FAQ)

If you use your knife frequently then it is recommended to sharpen it once in a while. A sharp knife cuts through anything more effectively. On the other hand, a dull blade needs you to put more pressure that in turn increases the chances of the knife slipping from your hand with greater force. So, a dull knife may be more damaging as compared to a sharp knife.

Many companies such as Gerber and Rapala, can sharpen your knife and ensure that the factory edge is back on it. The cost of sharpening would differ from one company to another and you need to pay shipping charges as well.

Saltwater is very corrosive and tends to destroy all types of steel. Many saltwater knives available out there are made up of high-quality stainless steel but they are also not 100% resistant to rust.  Moreover, if a stainless-steel knife is not maintained properly it might become prone to rusting. So, proper maintenance is crucial. Clean your knife and once it is dry it you should apply oil on it so that it does not rust.

In case your knife comes in contact with anything that you are not sure about, it is good to wash it with tap water and then put oil on it.
