I've got an older 5/8, square point, straight marked 77 (followed by a strange symbol) "G. Felix. Solingen, Gloriawerk" on one side of the tang and "Made in Germany" on the other. I cannot find any reference to this maker--any ideas?

It's in fair shape, but looks as if it was subjected to an overzealous cleaning with a dremel type tool--there are very faint abrasion marks and the blade was overheated in one small spot--a bummer since it has relatively little honing wear.

I am just curious as to it's history...

TIA
