It's a household combination tool. Yours is missing the knife sharpener bar, corkscrew and maybe a glass cutter.
Pointed end is a can opener.
I have several variations most seem to related to a glass cutter patented in 1869.

Here's some examples from my collection of household combination tools. It look's like skylab's is similar but slightly different than the second down on the left.
Top left is marked "Pat. Aug. 24, 1875", bottom three on the right are marked "Pat. 1902, 1903. Made in USA" and one on top right is marked "Pat. 09". Rest are not marked. All the ones on the left have a small glass cutting wheel on the ends.
Skylab, Are you sure there isn't a small glass cutter on the end opposite the can opener? Looks like something is there.

Whoa, how did I miss this thread before?? Nice collection there Bus! I've got a couple of those somewhere....I'll have to go find them and do a little side by side with yours to see what I've got.
In the mean time, I do have something similar to the one in the lower left of your photo close at hand. It was called the "Useful Tool No. 12" (I dunno if there was ever Useful Tools No 1 thru 11....?)
