Hey All.... I remember ...I think....back in the late 1980's or early 1990's at Fred Baker Firearms the Spivey Sabertooth Knife. I believe Mr. Spivey lived/lives in Guthrie?? Anyone buy one of these? Pro & Con on this style of knife? I remember he wrote a book about riding a horse across the USA and cutting his hand/finger, which is how he came up with this design.
