From the area estate of an individual who was born in 1933 and was a vet, county coroner, and deputy sheriff. I do not know if they were handed down in the family or how they were obtained. Two knives remain in the case. Unmarked. One has a single edge, one a two sided edge. They are sharp given their condition. Wear to metal- spotting ect. I have not cleaned or tried to improve. As shown and as found. I do not know anything else about them and am no expert.
