The one with the holes and slits in it is pretty small like the biggest hole is maybe 3/16" at best.  The other piece with the step grooves has a threaded hole in the middle of it.

Don't see the pictures??

The last one was too easy. So he's making us guess without looking now...; P

Could be an animate object, say a cuttlefish.  Whaddya think?

Well, I dunno, could be a set of these: http://www.google.com/patents?id=wtFZAAAAEBAJ&pg=PA2&source=gbs_selected_pages&cad=2#v=onepage&q&f=false

Is it bigger than a bread box?

wire gauge?

Gotta quit posting stuff after I've fallen asleep at the computer, boys.  I deserved every bit of that!!!  Well, I coulda said I was waiting for a plausible answer for the last one before I did pixx of these two, but I decided to man-up for a change....

Photos forthwith:::::

Hexagonal one looks like wire and sheet-metal gauge block.  Other could be part of larger assembly, maybe part of a clamping or positioning device.

Maybe I can use them as paperweights!!

Thanks Ron

Hex one looks like a bench block, for bending or upsetting various small objects, forming wire ends, etc.

More views of the other would be helpful

The hex block is a jewelers bench anvil. For forming metals
The other is just a part off something.
