Daggers are restricted from heavy utility use as the double edge inhibits the user from “choking up” on the blade, as well as not having a flat spine for pushing and prying. The classic Bowie blade is a decent design for moderate to heavy camp work, but the upswept tip makes it less desirable blade for tight work or hunting.

The fighter-style blade is not only good for combat. Many consider it to be the ultimate blade shape. A drop point, sharpened clip and concave belly curve combine the advantages of both fighting and camp knives.

Persian and tanto style blades are also well-suited for combat. Some would swear that the tanto is the foremost tactical blade, as long as you are not skinning or carving.

From its strong Viking heritage, the saex was a general use knife designed with several specific purposes. Its straight cutting edge works well on the longboat for cutting patches or sails. Its downward push through flesh when stabbing giving a broad ugly wound, crippling enemies.

I cannot stress enough the importance of choosing the right tang. For heavy-use blades, a full tang is the way to go. It is as stout and strong as it gets. Both the hidden and screw tang are weaker than a full tang, but have their uses. Daggers, antler and bone handles and blades that will face light to moderate use are all suitable for a hidden or screw tang.
