Friedr Herder Knife

[cookieha]

Difficult to learn anything about it and so I thought maybe someone here could help. It is an F Herder Solingen. The blades are Constant. It is a very thin knife. On one side there is an image of a factory with the word Werkanlage. I believe that means little factory. On the other side, is the Piskas (spade) with Anno 1727. I assume that is a date. In the middle is the fork symbol, the bottom is crossed keys with Anno 1848. I have photos below. Thank you for any info you can provide, we appreciate it. Really would like to find out what it is worth

Welcome here, cookieha.

Nice little knife you have there.

If you do a "search" you can find more about F. Herder.

I believe cookieha "borrowed" the posted pictures from this post.
