Finally got my 2 new Superknife Edges, a black one that looks just like bruner's and a blue one with the older handle style. The black one will not securely hold the blade during heavy cutting, seems okay for lighter cutting. In fact, I can pull the blade out with my bare hands if I pull hard enough.
The blue one is fine. Ease of opening and lock up are fine.
I wish I could find my old black Superknife!
