Furthermore, titanium dive knives can retain the sharp edge for a longer period and do not require regular sharpening. However, the Titanium blade is expensive compared to the stainless steel blade.

A lanyard hole is helpful as it allows you to wrap the knife to the other gears and around your neck. However, you will not find all the titanium dive knives with a lanyard hole. So, make sure you check before buying.
