Another thought...
If the knives are to be users for daily or frequent carry, then sanding might be an option later on, after the blades accumulate the inevitable scuffs or scratches or sharpening marks. Satin-finish blades are pretty easy to 'clean up' of scuffs & such, using something like 220-grit wet/dry sandpaper. So, if the day comes when you'd like to clean up the usage wear on the blade, that'd be the time to go after the unwanted etch as well.
On the other hand, if these are to be display/curio/safe queen items, I'd just leave them be. Any alteration to the blade, it's marks or finish will immediately damage whatever value they'd hold to a collector, if the knives are eventually sold as collectibles.
