In the "For What It's Worth Department" (While I was helping to judge the NASP Archery Tournament at the Bell County Expo Center, near Belton TX on 22 & 23MAR17) I was lucky enough to have been shown & was allowed to handle a very similar knife to the one that you pictured in Post 1577668. - The knife has an about 8" blade, is "really Plain Jane" & is handled in swamp oak, btw.
The knife was originally the property of Endurance Bain, who emigrated to Texas in the early Spring of 1825, settled in what is now Panola County, later briefly served in the Texas Revolution at the Battle of Medina and some years later was a town marshal & "livestock trader".
Mr. Bain passed away "of advanced age & infirmity" in the Winter of 1862 & was buried at the Methodist Cemetery near the village of Dotson.
The current owner, Carlos F. W___________, is a direct descendant of Mr. Bain & he said that he believes that his ancestor had the knife made at Captain Shreve's Port (Now Shreveport, LA) on his way to Texas from Pickens County, AL.
Note: Servicemen from that family have "carried that knife to war" at least during WWI, WWII & RVN.
(The current owner carried the knife when he was a member of the 23rd Americal Infantry Division during The War in VietNam.)
Note: The current sheath was made during WWII by a member of the USN & is marked with the name & SN of Carlos' father.
