Of the CPM M4 knives that I bought , which is everything up to but not including the 806, the M4 guacho is the best finished, and sharpest out of the box. With the 710, and 760 I had problems with the G10, alignment, the framelock, and with the 760, edges around 50-60 degrees inclusive.
The Guacho was the only one really finished to benchmade standards IMO. My two are really great users right out of the box. Can't say the same about the next two. Joe
