278. Used in a "tumbling drum" of some type for rust or scale removal? Maybe
dump a bunch in a concrete transit truck to remove caked on concrete?
279. Bicycle wrench/tool. Openings for wrenching axles & spokes, tire iron
on other end.
280. Electronic metronome.
281. No idea.
282. Strainer. Looks almost like the one in the shower drain.
283. No idea.
278 is a lodestone, or perhaps an iron meteorite, or perhaps both.
279 is a bicycle tool. The thin end is a tire iron.
280 is an electronic metronome with provision for tuning to A440.

278 looks to be a meteorite
279 is bicycle tool
280 metronome with the correct Italian music notation
281 looks to be a serious version of an oyster knife
282 might be an aerator from a sink faucet
283 is a can opener though I don't recognize the device on the non

A tough batch -- at least for me.
I'm posting from the rec.crafts.metalworking newsgroup.
278) It looks to me like an iron-based meteorite, with the surface
contours resulting from the heating as it fell through the air.
279) A custom wrench for some particular tool. It looks as though
the handle end is intended to serve to lever something up. I
think that the central open end is a bit larger than the hex.
The notches to either side may be tiny open-end wrenches, or may
be intended to bend something to adjust it. Is this another of
the items from that typewriter repair kit?
280) A combination tool for a musician. It seems to be primarily an
electronic metronome, with the ablity to select rhythms as well
(perhaps a virtual drummer), and a source for an AD0 Hz tuning
281) I think that is a fisherman's knife. The notch on the tip is
for removing a fish hook from the fish's mouth. The notches on
one side are for removing scales.
282) You say "extreme close-up", but you don't give the dimensions.
It looks as though it has been bent or trimmed along one edge
(at about 4:00 or so). Depending on scale, it could be a plate
for the output end of a meat grinder, or perhaps the aperture
plate for an aerator for a faucet. The holes are to the wrong
scale for it to be the aperture place for a hose and shower for
283) This is a strange one. Looking only (or mostly) at the second
photo it looks as though the spike on the end could be stabbed
into a stuck lid or a jar of mayonnaise or the like, and then the
handle rotated down to drive the second spike into it to get a
good leverage for unscrewing the lid. But if so, I don't know
what the feature at the other end of the handle might be.
Now to see what others have answered.

281: Grapefruit segment loosener/seed popper-outer; at least that's
what my Mom used ours for. ;-)
282: 125 _microns_????? That's not a close-up, that's a micrograph!
I'll be chomping at the bit for that hint!
281 wasn't made to be used on grapefruit, she might be amused to hear what
it's actually for.
I don't know if this is much of a hint, but what you see in the photo is not
the whole object, you are looking at a cross-section of something. I'll try
to come up with another hint in a day or two if no one gets it.
Btw, thanks to Badger for sending this photo to me.
