This is a silly bit of weird false nostalgia. I seem to recall that you are a fellow HEMA practitioner. Go look at some period rapiers (not reproductions). The fit and finish is excellent. For that matter, go look at some period bronze swords - same. The expectation of rough finish for higher-priced items because they are for "hard use" is a modern concept. ("Higher priced" in this case meaning: no non-knife knut is going to spend this much on a knife in this category - they will go buy one of the big Buck knives, which will work pretty well and have a finished spine, for less than this.)
You're right, there were and still are exceptional intricate pieces, especially some of the more fancy ornate swords, I do collect antique swords and knives as well. There's different grades of sword though, the very fancy non regulation swords usually officers, nobles, royals, aristocracy would carry very fine pieces, they would also pay a very pretty penny for them.
Your average peasant, conscript or anybody lower than a "Man at arms" position would typically have less fine swords and daggers etc, even pocket knives and such would be more rough utilitarian and bare bones.
I've seen some amazing blue gilt officers swords, and seen Italian, British, French, Hungarian etc swords in displays, some of them are true works of art (Well at least on the show side, the hidden sides on the non show side were sometimes unfinished, because nobody see's that part of the scabbard or sword when carried.
That's why I distinguish two types of well made blades, ornate show pieces (still functional, like custom gilt officers sabre) then you have basic infantry or regulation equipment, made by companies like Pillin and Wilkinson etc, or local production. These would be much lower grade.
I'm not putting ornate show pieces Vs functional utilitarian.
I'm saying there used to be an accepted difference, now in the modern world, everybody wants royalty level, even when performing dirty grunt work. Good quality and fully functional doesn't have to mean custom officer grade gilt sabre, there is still a place for regulation functional utilitarian, but if a modern person sees some rough forge marks, or a little kurouchi or rough spine they freak out, even though they claim they are going to be getting down and dirty with the tool hardcore op style.
It's funny as well because if you take say the Sebenza 21 community, which I am a part of. You will quickly find out that hardly anybody likes the sand blasted sebenza fancy finish on the scales. They prefer when it looks like its been 10 rounds with a grizzly bear looking scuffed up.
Chris and Tim Reeve should have just kicked all the 21's across the workshop floor before sending the knives out, to make sure the finish is nice and scratched up. They basically wasted thousands in finishing costs.
