I've been thinking about this with no real answer. Your description immediately made me think "Split Tail", but that didn't really sound right to me. Then sitting here thinking tonight as I couldn't sllep I decided to do a little research into Chattanooga in order to relate a name more personally to you and your home town. When I did the google search for "Chattanooga, Tn", the first thing to come up was a map and the first thing I noticed was "Ridgeside" in bold print. Ridgeside would be a good name for a knife, but it sounded too familiar, so the search continued.
I did a search for local tourist attractions. When I searched for attractions in the lookout areas I came across information on the "Cravens House", the home of Robert Craves. As you know this is a historical monument which was used by both Union and Confederate armies as a lookout point during the Civil War. Cravens' charcoal iron works was a driving force of the early economy of Chattanooga.
Of course, ince I read of Cravens' iron production I knew I had to relate this to a name. I decided I like the name "Craven". The deffinition of craven being "defeated, lacking courage". This would imply that a knife by such a name would strike fear into its' opponent, rather it be an advesary or object to be cut.
So, my nomination for the name is the Haney "Craven".
