Life is full of speculation. We get up in the morning and then "speculate" we'll live to the end of the day. Lighten up. ;-)A-freakin-men! I'll bet people back "in the day" weren't real concerned about being so P.C. as people are today. They couldn't just fire up their computer and order up a patch knife from TOW. I have several examples of metal arrowheads from my great grandpa's collection that were made before the first transcontinental railroad was built. It wouldn't take much thinking for one of the early pioneers to use a blade or other hunk of sharp metal to do anything he wanted to with it. Just making a point. If you want to believe otherwise, that's up to you to have your opinion/speculation also I suppose . Peace!!
In Neumann and Kravic’s Collectors Illustrated Encyclopedia of the American Revolution, on page 240 fig. 1, noted in the text of this reference, these wide bladed folding razors frequently did double duty both as a razor and as a patch knife.
That's according to Neumann, so my "speculation" is at least attributable to a source, instead of something I pulled out the air.
The NPS Virtual Museum is linked here. The NPS attributes the razor as being from Neumann's collection, and some razors were also used as patch knives.
