So true about a dagger.
Some point to ponder.
First and foremost it's a thrusting weapon.
So naturally the thickness of the blade matters.
For instance...
If you don't want it to bend over, than it has to be stocked removed into shape from a piece of thick steel bar. And that calls for a near perfect grinding away into a reasonable diamond shape profile.
Then, if you wanted it razor sharp - this is going to be a problem because a thrusting weapon like a dagger rarely is wider than an inch. Because of this and the fact that it has a thick stock with four sides, it becomes a challenge to ground an edge to satisfy cutting and slicing. So it becomes necessary to have a wider blade for that purpose. And that would include Boar hunting daggers or a Bocker Smatchet which measure as wide as 2 inches and above. There is a relation between thickness of the stock and width of the blade in order to come to an optimum angle to sharpen. Oh! And let's not forget overall blade strength.
So the A-F daggers are just great for the purpose thay were designed for. Notably a combat weapon fit for service.
