>853. Firing pin
My first thought was for a firing pin too (as several others
have suggested), but...
The business end looks like one used for a rimfire, but
wouldn't a rimfire pin be offset to hit the rim? This one
looks to be centered.
Most firing pins I have seen are longer in the narrow
striking area. There wouldn't be a whole lot of room behind
this one for the bolt to contain pressure.
Just some thoughts, I don't have a better answer...

Early yesterday morning I changed my answer to "thickness gauge", I agree
that micrometer wasn't the best description for it, though some tools go by
several different names depending on where you live, so I tend to be more
concerned about the use for a tool than what it's called.
I also modified my answer for the firing pin, and added the link below that
explains rimfire ammunition:

Thanks, I took the Krag reference off of the answer page.
Update on number 854: thanks to Leon for finding the patent number for it,
meat tenderizer was the correct answer:

Actually, by definition 857 IS a micrometer. So is your example. So is an
instrument
that measures small increments of ANGLE. Lots of things qualify as
"micrometer"

I believe you're right! I'm surprised I didn't notice that, as I'm
here at home waiting for the weather to warm so that the glare ice on
the driveway will melt some so I can drive to work. Fortunately the
car is in a garage so I won't have to scrape before leaving.
I was thinking it looked like some kind of splined miter joint -- but
in plastic?? Nah . . . .

O.K. Posting from rec.crafts.metalworking as usual.
853) Interesting. Looks sort of like a key, except that
when it is turned counterclockwise (from the spring end), it
will cam in and press the screwdriver tip harder into the slot
in which it is (presumably) engaged.
Not really sure why the spring around the rest of it.
854) for guiding a set of lines (ropes) parallel. Perhaps
for winding a rope evenly on a drum -- though I would expect a
mounting instead of a handle for that.
855) Looks like a tool for nipping a nail or a rivet to length.
Not sure what the plates below it are for. Perhaps jaws for
*pulling* nails?
856) No clue -- and it is way too late to take more time trying
to guess.
857) A device for measuring thickness of materials -- 0 to 1/4"
(0.250"), in both 0.001" increments, and in fractional inch
increments of 1/64th of an inch.
858) Another version of a "cork socker" -- a tool for re-installing
a cork in a wine bottle. It looks closer to the one which I
have had since about 1970 or so, except that mine is dark wood.
This is the second of these in the past month or two, IIRC.
859) A relay for interrupting current through an inductive load, or
for fairly high voltage. (This because the double set of
contacts in the current path doubles the opening that the arc
needs to jump to keep the current flowing.
Now to see what others have answered, and then go to sleep. :-)
Enjoy,
DoN.

853. Firing pin
854. For shaping and cutting dough or pasta into strings.
855. Metal shears for notching and cutting plate.
856. No idea. Looks a bit like the side of a heatsink.
857. 0"- 0.250" stand mounted dial gauge for thickness testing. The flat
anvils indicate it would be ideal for measuring wire rather than sheet.
858. Bottle corker
859. Electromagnetic relay or bell.

I'd like to point out that 857 is NOT a micrometer. As I said in my post
it's a stand mounted thickness testing dial gauge. A micrometer is this.

... which says "especially one based on the rotation of a finely threaded
screw". That's the only definition of micrometer that an engineer would
understand. Dictionary definitions are all well and good but many of them
are either too new to be in common usage or too old and no longer in common
usage. To an engineer a micrometer has a thimble and anvil and a dial gauge
has ummm... a dial.

O.K. I have no experience with disassembling a Krag (which I
thought used a centerfire cartridge, and this is for rimfire from the
shape), but I do know that at least it is *not* the firing pin for the
HILTI model DX-350, which I have, and which I just disassembled to
refresh my memory. I don't know how many other models of nailset guns
HILTI may have made.
I do agree that it is probably a firing pin for some flavor of
rimfire weapon.

I agree. In the field in which that instrument was used, it
would not be called a "micrometer". "dial thickness gauge" would be the
most likely term. It has a lower range, and requires less skill to read
than a micrometer would. That covers 1/4th of the range of the typical
micrometer.
Enjoy,
DoN.

I believe #856 is an ice scraper, the plastic kind one carries in the
