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.
