There is something stamped on the side of it, maybe letters.

Interesting guess…it does look like it means business…and turns out it does!

So I looked again, and this is a guess but… it looks like it belongs on a construction site more than in your Victorian dining room so I am going to say it is a wedge to hold bricks apart while crafting an arch.

Your first comment reminds me of all of the ridiculously/wonderfully specialized utensils there used to be among wealthier Victorian-era folk. Bon bon scoop, fish slicer, crumbers, butter pick, mustard spoon, egg spoon, grape scissors, pickle castor, tomato server, cheese scoop, asparagus fork, lettuce fork, berry fork, fish fork, melon fork, bacon fork (yes, a fork for bacon only)….here are more by Victorian-era silvermaker Reed & Barton.

Perfect site for fitting out your table if you don’t mind paying $50 per piece.

Seriously I have no idea. Neither side appears to be hand-friendly and neither side appears to want to be struck by a hammer. I am stumped. Laura, is this to be used in conjunction with another tool? (Yes, that’s the same as asking for a hint.) Don’t answer though as I would like to see if someone will get this without help
