Is this the ancestor of the modern one-piece multitool? It's about 4 inches long, and the design looks like something made today, but it isn't. MUCH older than that.
Found this on eBay today. Thought it was a contemporary design, but it's not. Swedish American Telephone Co. went out of business ca. 1920; so it's a hundred years old or older.
The mark (partially cut off) reads "SWEDISH AMERICAN TELEPHONE CO CHICAGO"

You have many features and an overall format similar to today's MTs.
A ruler
An alligator-type wrench as found on tools like the Pocket Wrench II
A nail-puller/pry bar/big slotted screwdriver
A bottle opener--which there's few that don't have these tools these days
A wire stripper; or perhaps a cigar box opener
A contact file on one corner of the tool
Specialty wrenches--I think the square one is a Prestolite key, I don't know what the other, longer opening is for.
Presumably, this was a "necessity is the mother of all invention tool" designed for their telephone personnel to cut back on weight.
