All About Pocket Knives

What is this knife? What would be the value? It has PAUL WEYERSBERG & CO SOMNGEN ROSTFREI on the blade. The logo is an oval shape with a sword facing down and greenery around it. It is some type of switch blade that slides out from the front out of the handle. See attached if they are clear you can see the logo on the blade. I am assuming it is some type of German made knife.

AFTER POSTING I FOUND THIS INFORMATION SEE BELOW

Fallschirmjäger-Messer, Paratrooper's Knife (Item WEHR 10-3)

DESCRIPTION: One of the forerunners of the employment of airborne force, the Wehrmacht provided these elite troops with the best equipment German technology could produce, a good example of which was the specially designed paratrooper gravity-blade knife, an exceptionally practical item of rugged, but excellent quality. This one that we offer is also exceptional in condition throughout. Again, I hate to use the "mint" word, but since this seems to be an excepted phrase in our field I'd almost have to express it (this is mint!). The blade is clearly marked Paul Weyersberg & Co, Solingen and the Rosterrei statement under the logo. The spring is quite tight and what can I say more? It is a honey!

Rob,

It's a gravity-knife, from the WW II era. If it's got a swastika and eagle, it's worth more to the people that like those kinds of things. 20, or so, years ago they were seen occasionally, and had some demand - in the $75 -100 range. Today, I have no idea.

That's about all the help I can provide,

JR
