This type of knife was used by the Germans in both WWI & WWII.
I cant say, when your knife was made though.
It seems like it is made by "Gottlieb Hammesfahr Solingenfoche" because I found the same exact knife with one different marking than mine in the same spot labeled as WW1 boot knife. and it seems to have to same makers marking but it is so worn down.
The thickness of the crossguard, the rivets, the quality of the metal used, the quality of the leather, the markings, the workmanship....they're all screaming : PAKISTAN
Sorry to say but this one is a repro, this type of WWI german combat knife (Gottlieb Hammesfahr Solingen) is one of the most faked knife on the market.
I hope you didn't pay too much...
