These two combination tools seem to show up at auctions from time to time, but never both of them at the same time it seems. So for several years I just assumed they were both the same tool, but with different markings. Turns out I was wrong. I finally managed to get one of each, so here is a little side-by-side photo op.
LEFT/UP:
The Ranchman Combination Tool, produced by Straight Mfg. Co. of Jamestown, New York. The earliest reference I've found to this tool is an ad from 1903.
RIGHT/DOWN:
Combination tool produced by the National Hatchet Company of Marshalltown, Iowa. Earliest reference is from an 1907 advertisement.
The most obvious difference between the two is the area right below the pivot, where the National Hatchet tool (marked DROP FORGED TOOL STEEL) has a flat "plier" area with a couple of crimping grooves. The Ranchman (marked FORGED TOOL STEEL) has no such plier area.
On the reverse side, the Ranchman is marked RANCHMAN. (Some of the same tools are found today marked K.L. RYMAN NEWARK N.J.)
National Hatchet Tool is marked MARSHALLTOWN, IA. PAT'D
At the far end of the handles, both tools have a curved nail/staple puller notch, and a flat screwdriver. Notice the orientation of the screwdrivers differ by 90 degrees. Also note that both tools originally had a leather hole punch partway up the handle, but these are broken off on both of mine.
