I don't know what kind of blade is in the knife and I don't know what pattern the knife is...the blade opens and has a stop...
You would have to keep your finger on the blade so it won't close...I can't figure out the function and purpose for the knife or razor
If it's a razor it's the smallest I've ever seen and the blade dosen't resemble a straight razor blade and It doesn't look like a doctors scalpels
Goins book pg 87 states the stamps dates 1873-1890 a trademark used by Friedmann & Lauterjung
I'm not sure about this one hopefully someone knows more about this than I...
