Well I am a Dive master and master SCUBA diver with over 1,500 dives.
A dive knife has several uses underwater, stabbing sharks is not one of them
Depeding on what type of diving you are doing you may find the flat tip more useful. Probably the best design I have ever seen in a daive knife is the U2 design by Kit Carson. The Buck version Intrepid is pictured below.
The flat tip is used for light prying and it works great on Abalone shells too. The number one reason for having a dive knife is to cut yourself out of monofiliment line, which is a divers #1 under water hazard. The U2 sharpened false upper edge is perfect for this in that it will hold the line in it's recessed area.
I am testing a U2 now made from Talonite, thanks to Rob Simonich, Kit Carson and Walt Welch. The results will be in a upcoming "To The Point" issue.
A regular style blade will do fine but if you ever use it to pry (which you will), you will end up with a flat tip anyway
Remember when you are underwater you are limited to only what you brought with you. You can't run back to the garage for more knives or a pry bar and you do not want to surface either as that counts as another dive. My advice is get a flat tip.
What I would like to see it a underwater multi-tool made out of Talonite!
