All About Pocket Knives

I found this several years ago with some of my grandfathers old tools. I was knocking the rust off, and to my surprise, I saw "Solingen" on the blade with "Germany" underneath. I can find no other identifiers anywhere on it. Synthetic handle. Solid little knife. Anyone know what this is?

It's what you say.......nothing more.

You can see plenty listed , and SOLD on ebay, I'm sure. But it's no more than what you said.
