All About Pocket Knives

Ok, so I went to the swap meet today, and this is who followed me home.
One side of the tang says “Made In Germany” and the other says “Gudedge” with “Solingen” under it and 564 with possibly a “T” at the bottom.
The handle is stacked and you can see the coloured layers at the blade end. They are cream and red. The guard seems to be brass.
I can’t ding any reference except “Imperial Gudedge” and there seems to have been no Imperial in the stamp.
It’s a solid little thing. My neighbour swears it’s worn down but looking at the way the striations and angles are on the blade, and the way the lettering is placed, I’m not so sure. I suspect it was pretty narrow to begin with. It’s also quite even on the edge. I’m still working on the residual rust and crust but to my surprise, it’s still pretty darn sharp!

Ok, any ideas? Thanks!

Oh, before anyone says it’s a hunk of junk, that’s ok with me. I only paid $5 Cdn for it!

No ideas? Like I said, all I can find is Imperial Gudedge and I don't see any sign of Imperial on it anywhere. It's obviously old though. Ballpark? Anyone?!

I'm afraid I can't help with Gudedge.
The blade looks to me like it is about 40% gone.
The bird's head pommel just yells "pre-WW2" to me.
I like it!

That actually does help. Pre-WW2 is what I'm hoping for. As always, it's age, not price or condition that grabs me. I just scored a big old dresser with a wardrobe side from the neighbour at work. It's damaged and kinda overused and in the way, but if its a minute over 1930, I'll eat it! I'm in love!

Thanks for the reply!
