Help with Knife Identification and Age??

Hi, could sure use some help with this folding knife. I have looked all over it and no marks that I can see, it was in with a lot of old Civil War surgical items, though I'm sure it's nowhere near that old. It is 5" closed, and 6 3/4" open, single-edged blade, all the fittings appear to be nickel. THANKS for any help you can give me on this!
