Evidently the Buck 110 is indeed a copy of some previously made knife in the 1840s.
Texas Ranger McCrea is seen in the recent episode of the Lonsome Dove TV series, Commanche Moon, sitting atop a cliff in the Texas badlands whittling with what appeared to be a BUCK 110.
Since the Buck family didnt start making the 110 until the early 1900s, I must assume the 110 is indeed a "copy' of yet some other knife of unknown manufacturer.
