Knives & Line Cutters

Diving knives and line cutters are essential kit for all divers. You may not need them often but when you do they will prove invaluable. There’s a large variety of diving knifes and line cutters available on the market which can make it difficult to make a decision when purchasing.

Below we have outlined some of the key features to help you find the right product to use when diving.

Line Cutters – Compared to diving knives line cutters are specified for one particular task, removing and cutting through lines, wires and other obstructions whilst diving. Line cutters come in many different styles and designs and are usually completely composed of plastic on the outside with a small, secreted groove containing the blade. This designs makes them easy to manoeuvre, twist and pull underwater which explains why they are popular among many divers. Compared to steel and titanium diving knives, line cutters are often significantly cheaper and potentially safer to carry around in between diving activities. 

Steel Diving Knives – Steel diving knives are available in a number of different sizes and specifications. The main factors to take into consideration when purchasing a steel diving knife are it’s purpose and your budget. If you are new to diving or dive infrequently a normal steel diving knife will often suffice. If you dive regularly and want a reliable, long lasting diving knife then a stainless steel knife is likely to be the right choice for you. Although stainless steel diving knives are more durable than their steel counterparts they still require regular maintenance to keep them reliable and in working order. If you have a folding stainless steel knife make sure to leave it open and exposed to the fresh air. Clean the blade with fresh water to remove any sea salt and other residues and condition the blade by coating it with oil periodically to keep it in peak shape.

Titanium Diving Knives – Titanium diving knives cost more than stainless steel versions which means if you dive frequently you will get more value for money from using them. The main reason for the difference in price is that titanium is much more resilient than stainless steel which means that titanium diving knives require much less maintenance to keep them in working order. There are a large number of different titanium diving knives available on the market, choosing the right one comes down to personal preference in terms of budget and also the style and size of blade. Choose a knife that fits comfortably in your hand that is easy to handle and use when under water.
