I'd think laser or waterjet will give the cleanest 'as cut' edge with minimal distortion, however I'd think you'd really need to get them ground after that to get a clean edge.
However I'd guess laser/waterjet will be pretty expensive unless you go for a large batch. Grinding would involve somebody with a surface grinder and small vice.

Magnetic chucks are only any good for items with large flat surfaces, not holding a small flat bit on edge.
A small vice mounted on the magnetic chuck, with the metal spaced appropriately would work fine.

It would be fine for that, but not for doing the edges which is what the OP is looking for.
One option would be cut them from slightly thicker metal, then grind them to thickness.

Or stack multiples on edge together and grind the lot?
If the nagging gets really bad......Get a bigger shed:naughty:

I am wondering here if my lowly cnc machine could be pressed into service to get a reasonable finish on on the top visible edge ....drop a part into a pre cut slot on a holding jig....tighten a couple of holding screws, then run a dremel (fitted with a grinding wheel) along the top edge to a very fine depth? (the depth being so minute, that I doubt my machine would get stressed?)
