The owner's description of this device:

It is obviously a cutter or trimmer for something – but what?

It has two “pressure plates” that hold whatever is being cut in place. When clamped, these round plates rotate in either direction and can be locked on each quarter turn. You can’t see the lower plate as it’s immediately below the upper one you see in the picture. The spring-loaded thumb lever on the lower front inserts a pin into an indent in the lower plate to hold it in place – for trimming, I assume. There are only four indents to lock into – one every 90 degrees around the plate. The top plate is spring-loaded in the up position and is locked down by pushing down on the handle located between the springs.

The trimmer has a maximum cut of about 5”. If something flat and trimmable less than 5” (and more than 4”) in both directions is slid between the plates, clamped down, and trimmed on all four sides, it ends up being a perfect 4” square.

What is this thing meant to cut? And why does it have a walnut carrying case?

...I was hoping to find some manufacturer’s marks but there is absolutely no mark of any kind on the whatsit nor the case. The bulk of it is made of cast aluminum, I think.
...the plates are slightly notched like a fine file and would mar a photograph.
