A dive knife is not a weapon, it is a tool...
The main point to understand is that a dive knife is not a weapon, it is a tool. It should never be used to harm or touch aquatic creatures or deface the underwater environment.
The most important use of it is to free yourself or your buddy in case you get stuck in a fishnet or with vegetation.
For most recreational divers, blunt tip should be fine. And better not to puncture your air hoses or wetsuit!
One advantage of the titanium is that it pretty needs no maintenance. The knives do not rust and are corrosion resistant. They are lighter, more flexible and harder to break.
Titanium is the high level choice so it is significantly more expensive.
Stainless steel will need maintenance not to rust. It needs to be cleaned with fresh water, dried and oiled or rubbed with silicone after each dive.
You'll have to choose between 300 or 400 series. The lower the number, the more resistant the blade is to corrosion. However, a lower number blade will loose its edge faster.
You should rather go for a medium size (4 inches).
Smaller ones can fit anywhere but make sure you can grip the knife securely.
Bigger ones can be too cumbersome and dangerous.
The medium ones are the more practical, and they can be strapped to a variety of easy-to-reach locations.
