Can anyone put a name to this?

A tool dealer had 4 small metal wedges.
Each was around 3" long, 1 1/4" wide,
and tapered from around 1/3" down
to 1/32".

This thin end was very neatly done; it really
was of uniform thickness across the whole
width.

The thick end was chamfered, presumably
to allow hammering without burring, like the
top of a punch or cold chisel.

The large faces were ground, with grinder
marks that looked to indicate around 8"
diameter grinding wheel. However,
the faces still had some unground area.

So, I'm guessing these were rough forged, then
finish ground.


If they were ground, it was likely for a sliding fit against each other,
two wedges pointing in opposite directions to make an adjustable shim.
But they're not ground the full length, so that makes me wonder if a
wedge goes between some other surfaces to adjust the space between them.

If the grinding wasn't done with a precision surface grinder, but only
cosmetically ground with something like a disc sander, then they would
more likely be some type of punch or chisel--or still be shims for less
precise stuff like woodworking.

Are there any markings on them?

Are they 15 degree wedges for physical shifting of something being clamped ?
Seems close and the rough measure of 1/3 would take care of error...
Typically they are used in pairs - on each side of the work.
