Do You Know What These Tools Are?

[onocoffee]

Today was the annual PATINA Show in Damascus, Maryland. For those unfamiliar, PATINA is the Potomac Antique Tools and Industries Association where they have a big tool market and auction. As you might suspect, it's mostly hand tools but a great place to get some nice deals. I won the bid on a lot that included a square, marking gauge (not as nice as the one I really liked and a caliper. These were the items I was interested but the lot came with some other tools that I am unfamiliar with: something that looks like a wedge, cold chisels and then items that are like hole boring bit or shaper bit with tangs on them - the kind of tangs you'd find in chisel handles. I asked a couple of the guys around be but they were unfamiliar with these steel bits, so I'm wondering if anyone here might recognize them?

Also included in the lot is something that looks to me like a specific gravity meter and thermometer combo. Seems like an odd pairing and wondering what kind of purpose that may have had.

Thanks!

The first image resemble heavy duty versions of the leather belt end trimmers that I have, though mine are kept very sharp.

Maybe these are blacksmiths’ metal band trimmers that work much the same way.

The last photo,

Upper left (below the wooden thing which is probably a hag’s tooth router) you have a round tenon cutter, the tapered square shank fits in an old style bit brace.
Below it is a masonry drill bit. You hit it with a hammer and then rotate it about 90 degrees and hit it again, repeat, repeat, repeat, etc.
Some wedge for ?
Center punch for countersunk holes in hardware.
Hole saw for bit brace.
Slotted screwdriver bit for bit brace.
Wedge for tightening fixtures. For example, back when nuts and bolts were rare forged pins were available. You might fasten a vise to a bench with those pins but they would have some play. You drive that wedge in the right place and tighten the thing up. This answer is pretty speculative…
Wooden file handle.
Not sure this is one but blunt edged chisel shaped tools used to be used for packing oakum into the loose hubs of cast iron pipes. After wrapping the thick crude rope like stuff into the joint and then hammering it down the joint would be stiff and stable enough to pour in some molten lead to make the assembly watertight.

The second is a hydrometer.

The others are stone working tools, the ones with tangs go in braces.
