Many divers are not in the habit of using a dive knife on a regular basis. Just like dive lights, dive knives are equally important tools that divers regret not carrying with them. Diving knives have the potential of saving lives during emergencies. They come in extremely handy for carrying out various tasks while being underwater. They can be used for cutting entangled animals out of bundles of ropes or lines and can equally contribute to preserving the ocean. However, with different varieties of knives taking over the market, it might get a little challenging for you to come up with the right choice. The points below will take you through important considerations so you will not have a tough time picking the right one.
Plain Vs. Serrated Edge
This is an important debate that you need to consider when purchasing a good quality diving knife. Both these blade edges feature varied uses. Since the diving knife cuts through strong materials and ropes, the ones with serrated edges might be the right choice. Nevertheless, you can choose the ones with straight or plain edges if you are more into cutting finer things and lines. Majority of the diving knives provide both plain and serrated edges on either side. Usually, you would not want this kind of knife, but because diving knives are not used for puncturing things, it is beneficial to have a blade for slicing things and one from cutting ropes.
Consider Knife Size
Another essential thing that you need to consider when buying a scuba knife is its size. The size that you should choose will completely depend on where you intend to take the knife. Dive knives generally range from the compact models that can easily be mounted on BCD pockets to the traditional full-size makes that can be strapped to the lower leg. You can go with any size that suits your expedition. Here the key is choosing a knife that is sufficiently compact to fasten to a BCD or hose in the form of a primary tool.
Determining a scuba knife shape generally involves choosing a blade tip that is either pointed or blunt. Recreational divers should go for blunt tip blades. Such knives can easily be stabbed through almost anything starting from a wetsuit to a hose. Pointed blades are perfect for spear fishing.
You cannot miss out on this significant consideration when choosing a scuba knife. The longevity and the performance of your diving knife will ultimately depend on the kind of material used for forging the blade. There are two common materials used for this purpose, and they are steel and titanium. The ones made of titanium are lightweight and strong while the stainless steel models can easily be sharpened. Titanium knives are corrosion-resistant but not as strong as stainless steel. Overall, both the materials are suitable, and you can choose any one of them. But, if you do not have enough time to maintain the knife, then it is better to go for the ones made of titanium.
A dive knife is not just another device. It is necessary for you to know how to use one properly before even getting it from the market.
