I own several “Mike Stewart Era” Marbles knives with the 52100 blade steel.
My experiences are completely different than what’s described above.

I’ve found fit and finish to be excellent as well as edge holding ability. One thing to remember is that these blades are “old school” handmade/assembled. As such, no two are exactly the same. I own 1 Plainsman and 3 Fieldcrafts. Each is unique but fit and finish of all of them is excellent!
Also, I’ve never owned a sharper knife.
The key to maintaining the convex grind on these blades is to touch them up before they get too dull. This is easy to do, when needed, and only takes about 5 min after a hunting trip or field dressing job to bring that edge back to hair popping sharpness. Easiest way I’ve found is to strope them using a neoprene rubber computer mouse pad and a sheet of 1200-1500 grit sand paper. Having said that, I’ve never felt the need to touch up these blades in the field. And, I use them for skinning and deboning meat only. I don’t chop, pry or use the edge as a screwdriver.🥴

Love the convex grind on these marbles knives!
