The lower CF is a good quality example, top, the working edge looks like he hit a couple of nails as he
was working the wood.
That other (cupcake) point stem being excessively long is just an illusion. Not sure what it is. The occasional Carrolton which have moderatly long stems have been found this far south..
If your campaining for a new point type, I'll vote for you, The CFREX point is original
