Not sure what you mean by work. We both use our knives for hunting, camping, fishing and as back-up for a rifle shotgun or pistol. Generally they dispatch fish or birds where a coup de gras with a knife is safer than a shot. As far as our carry knives are concerned my Dawson holds a great edge and his Magnum copy seems to sharpen easier that the S.O.G. Trident that I have.
The Custom mades, Colt, Fox-N-Hound, Smith, Steel Stag and Winchester Bowies are (like most our friends) put to use at the old west shoots, so we don't scratch them up (unless there is a Course of Fire that the shoot organizers sneak in on us, and then we use old beaters.)
My Dad used Customs, Ka-Bars, Morseths, Randalls, Russells in Viet Nam, so I guess he carried them for work (he is currently carrying a huge Thai knife (that cost less than $40) that reminds him of his unit's dive locker Randall Number 16-2 and saves him from rough use on his more expensive knives, which is what we all do as well.) Although a Dawson was meant for hard use...
Was that an answer?
