You want a dive knife that is sharp, strong and resistant to corrosion. If you're a scuba diver you should consider a blunt or chisel tip knife to reduce the chances of stick injuries. If you're a spearo you'll opt for a pointed tip knife so that you can easily dispatch your catch. Some divers also like to have a line cutter and/or shears, typically in addition to their dive knife.
