Titanium dive knives are lightweight, strong and highly corrosion-resistant, making them perfect for diving.  Although titanium dive knives typically cost more than comparable stainless steel dive knives, they require little maintenance and stay sharp much longer. 

Dive knives may have either straight edges or serrated edges on the blades.  Straight edges are great for cutting line and other materials that can be sliced.  Serrated edges are best when the diver needs to use a sawing motion, such as when cutting rope, kelp or similar materials.  Some dive knife blades have both a straight edge and a serrated edge and many dive knives also have a notch in the blade for cutting fishing line.

In addition to blade edge, divers should also consider blade style.  The most common blade styles are point tip and blunt tip.  A blunt tip dive knife has a flat blade tip, which is handy for digging or prying.  A point tip dive knife has a pointed blade tip, which is typically used for game, but is not suitable for prying (or it will become a blunt tip!).  Some dive knives also have a tanto tip.  A tanto tip has an offset point with an extended flat edge (see bottom knife in photo above).  Tanto styles can vary from manufacturer to manufacturer.  Divers using point tip or tanto tip dive knives should be careful to avoid puncturing BCD's or other gear.

Dive knives also come in a variety of lengths.  Compact dive knives typically have 2" to 3-1/2" blades and are often attached to a hose or BCD for easy access.  Standard dive knives typically have 3-1/2" to 5" blades and are typically worn on the inside of the calf, the BCD or sometimes the arm.  Large dive knives typically have blades that are 5" or longer.  These types of knives also have largers handles, which are very useful when diving with heavy gloves in cold water.
