Vintage Swedish fixed-blade hunting/skinning knife with a natural antler/stag handle and strongly curved skinner-style blade. The blade has a very faint, partially worn maker mark that appears consistent with "SANDV. " / "SWEDEN, " but the full stamp is not completely legible, so please review the close-up photos and make your own determination. Knife shows substantial age and use, including surface oxidation, patina, scratches, staining, and sharpening wear.
The antler handle has a great old handmade/Scandinavian look and appears solid from the photos.
