I can't think of the downsides to a mora combat knife.
They are light, stainless and quick to access.
I am not sure what a high end knife does especially better.
I mean, they absolutely would make an adequate knife. I have zero argument there; they're cheap, sharp, not all are stainless but that is also an option, and true they are quite lightweight. There is a good reason I own probably a dozen of them kept in the glovebox of each of my vehicles, my junk drawer, my fishing tackle bag, bug out bag, etc. If I was mass purchasing for others they would certainly be atop of my list.
If I was choosing my own carry though, for combat, their rat tail tang in a composite handle design would give me concerns about it's durability under extreme use, and while lightweight they are also kind of bulky, plus their sheath retention can sometimes be questionable, especially under the possible added duress from maneuvers they may see from a light infantry perspective, so I would personally prefer something in an equally tough steel but full tang, with a slimmer profile, and with a more secure sheath retention for peace of mind.
Does that make it a poor choice? Not at all! But there are potentially better choices that can in fact do some things better. Precisely why my personal choice, if I were to go back in time to my days in the infantry, would be an esee3 with molle sheath. Roughly the same size, Equally tough steel, equally sharp, full tang construction, a full 1/4" thinner, with a flatter profile, and better mounting options to vest or gear, with the added retention strap around the handle to help keep it secure from accidental loss like dislodging itself during maneuvers... From my own personal former infantry perspective, already rocking a fully combat ready packout in full battle rattle; plates, ammo, first aid kit, etc. that added 3oz., roughly equal to the weight of 7 more rounds of ammo, would hardly be the breaking point of how much one could carry at that point, but the small added benefits, IMO, would be well worth it over a bulky round plastic sheathed Mora with partial tang construction.... But I would absolutely and unquestionably take a Mora over nothing, 100%. I would absolutely give a Mora to someone who had nothing. Shoot, I might even throw the extra 2.5 oz. of the Mora into the bottom of my ruck as a backup option...
