Your knife is a model 594. The KA-BAR over OLEAN, NY stamp was used during WW2 but since your knife has an aluminum pommel and aluminum was not allowed for civilian use during the war your knife was likely made between late 1945 and sometime in late 1947 or early 1948 since that was about when the mark was changed to KA-BAR over USA. It is a civilian hunting knife, not a military knife as they are often called on ebay. The model 594 is first seen in folder (catalog) #36 which was published circa 1936 so it is not an early model. The pre war ones will have the Union Cut Co stamp on the back ricasso. Your knife is in very nice condition and the sheath looks original although it does look like the pommel nut has been tightened over time. The folders show finger grooves in the leather handle but this may be because the folders are pre-WW2 and later ones had no grooves. I have no wartime or 1946 or 47 catalogs or folders to confirm this but it is logical. If anybody does have wartime or early post war folders, catalogs, or price lists please contact me as I would like copies or originals for my library.
