Why Are Dive Knives Blunt Tipped?

August 22, 2022 3 min read

A dive knife's blunt tip is a benefit in many situations, including rescuing oneself or anchoring to the sea bed. A diver may also use a dive knife to knock over his or her tank. This article will explain the advantages and disadvantages of both blunt tip and sharp dive knives. We will also compare the size and materials used to create diving knives.

Benefits of a Blunt Tip

If you're a spearfisher, the benefit of a blunt tip on diving knives is clear. Sharp blades can puncture your wetsuit, and blunt tips can avoid accidental stabs to the body. Besides spearfishing, a blunt tip knife is useful for cutting ropes and lines, cleaning your boat, and more. It is also safer than a sharp knife for recreational diving, as it won't nick your wetsuit or hurt you.

Materials Used to Make Dive Knives

Divers who want a good quality knife should first look into the material. Traditional dive knives are made of various analogues of AISI 420 (420HC) and 440C (440C). These materials have been used for decades and have well-known qualities. However, these knives are not designed to survive the harsh environment of salt water and are prone to corrosion and rust.

Size of a Dive Knife

The size of a dive knife is critical. It must be easily reachable by the diver and should be big enough to be comfortable to hold while wearing bulky dive equipment. It should also be corrosion-free, with rust-resistant stainless steel blades. Check the blade for rust with a cleaning solution and wipe the surface of the blade with soft steel wool. It should also be lubricated with silicone if necessary.

Sharp Vs Blunt Tip

There are three types of diving knives available, each with a different purpose. A diving knife with a straight edge is best for cutting plastic, while one with a serrated edge is best for sawing through natural fibers. Divers should consider purchasing a knife with both a serrated and a straight edge. Similarly, a diving knife with a blunt or tanto tip is better for digging, hacking, and chiseling.

Materials Used to Make Titanium Dive Knives

Titanium is a unique metal. It is neither magnetic nor corrosive. A titanium dive knife weighs about 40 percent less than a steel diving knife. Moreover, it is much stronger and resistant to corrosion. Most titanium dive knives are blented, as they are blented with the process of metal alloying in powder metallurgy. Because of its unique properties, titanium dive knives have found a niche among professionals. Moreover, the knife does not require rusting and corrosion protection, which makes it a preferred choice for professionals.

Stainless Steel Vs Titanium Dive Knives

There are many differences between these two types of diving knives, including the materials used for the blades. Stainless steel knives are generally cheaper than titanium and can rust more easily. But if cared for properly, you can expect your stainless steel dive knife to last a long time. But do you really want to invest in titanium if you can get a stainless steel one for a fraction of the price?

Pointed Vs Blunt Tip Dive Knives

A diver's dive knife comes in two basic styles: pointy and blunt. While both styles can be useful, each has its own pros and cons. Sharper knives are generally more efficient at cutting through soft materials, while blunt knives are better for prying and wedging. The tip shape and size of a diving knife also affect how useful it is. The following are some tips to choose the best diving knife for you.
