Im assuming its to clean up bolt threads?, never seen these type before. Some chime in, enquiring minds.
Old stuff you still use.

The thread files come with various threads per inch (tpi). They are not for full re-threading as with a die, but for cleaning up damaged threads. My most common use case is when a thread, or a few, on the end of a bolt are damaged or folded over, but the remaining threads are okay. When that happens, a nut cannot get started on the threads, or even a die is hard to start.
To repair the threads, match the thread count of the bolt with the appropriate tpi face on the thread file, then following the existing threads on the bolt, use the file in a filing motion to re-shape the damaged thread(s).
Used like this. IMHO, a couple of these files and a set of rethreading taps and dies (not cutting types) is a must for anyone working on old cars.

Not used much any more as I have newer stuff, but still on hand if needed. Both purchased from JC Whitney in the 80s.

I have no clue what these are. Well, except the clue of michigan engine bearings.
I was thinking the first and third pliers are leather working tools. But I bet not.

In order of the images, this is each item pictured:
1. Piston ring expander pliers: When the handles are closed, the little jaw on each side closes on the ring at its gap, and the main jaws open the ring gap to slide the ring over the piston into the ring land.
2. Ridge reamer: Shaves the ridge at the top of a worn cylinder bore.The different rectangular attachments adjust the reamer body to fit against the bore and place the knife port on the ridge. Then it is turned with a wrench or ratchet/socket using the hex to cut into the ridge. It is cumbersome, and can be laborious because you are machining by hand, but it's really only intended for a small ridge on a cylinder that will not be bored out.
3. Ring groove cleaner: Used to cut built up carbon out of piston ring lands. Select the blade that fits the ring width, align in the ring with the guide on the other side. Ratchet inward, then turn around the piston to clear the ring land. The loop allows easier holding and turning of the cleaner.
4. Connecting rod bolt covers: Made by Michigan Bearings Company, these are placed over the rod bolts so when the piston and rod assembly are installed, the covers prevent the rod bolts from nicking the crankshaft journal. A couple of pieces of fuel hose can do the same thing, but these look cool.

I don't use it much. I bought it sometime in the 1980s.
I had a can of that somewhere - I may still have it!

Welp I don't use these anymore but just want to give a heads up to anyone looking for machinists tools as I'm seeing a ton of AD's on Facebook Marketplace mainly in the Northeast, prices vary I guess for Granpa's old tools.

This is my Dad's EDC watch when he worked as a brick mason foreman at Stelco Hilton Works in the late 50's. A couple years ago I got it running and now carry it in the watch pocket of my jeans.
I have a V-belt sizer too....it's all wood and looks like people with really dirty hands used it a lot lol

Unicorn 2500 Impact Driver. I've had it since the late 1970s or early 1980s, but it was used when I got it. It is ideal in some situations where it's too tight for hand tools, but an air impact, or other means might risk rounding out/off, such as the #3 Philips head screws holding the door latch assembly in many cars. I used it for this case today to remove screws, without head damage, that have been in place since new in 1977.

I have one of those from the refrigeration class that I took in high school.
I have a set too, just not like that. Use regularly!
They wonder what they used to straighten the fins in honeycomb radiators?
