German Fighting Knife WW1 - Shoemaker/Graben Dolch Solingen

Description

An original German Solingen fighting knife. Exact year of production is unknown.
It is made from a very high quality carbon steel. It is fairly sharp now.
I think a small piece is missing from the tip. There are only minor spots and nicks and scratches on the blade.
The scabbard buttons have rusted, but all in all very good considering its age.
