When Buying a Titanium Dive Knife

The use of stainless steel makes a dive knife heavy. This is the reason why most new scuba diving knife brands and models are made of titanium.

A dive knife has a holder called sheath with a quick release button and an adjustable strap where you can securely and safely fasten it in your body, which is typically attached on the lower leg part.

Especially the blade of a diving knife, is made from a material that can withstand the elements present in our diving environment, like salt which can lead to corrosion. Stainless steel is one of the conventional metal used in making a dive knife, and its anti-corrosion properties is made possible through the addition of carbon on its alloy. Titanium diving knives are generally lighter in weight as compared to their stainless steel counterparts. On top of the weight difference, another significant distinction for titanium diving knives is that they are virtually corrosion resistant. It is made up of a transition metal that has a low density but high in strength and can perpetually withstand the corrosive effects of saltwater and chlorine enriched water.

On top of selecting a titanium-based diving knife, you have to remember that there are certain features that you need to consider before purchasing one. The blade must have a serrated edge where you can use it to cut high-density ropes and small cables. It should also have a blunt butt which can function either as a pounding mechanism or tank banger which can assist you in calling the attention of your buddy and the rest of the group.
