Thread: Lap Spyderco UF on DMT 8EE?

Well, there appear to be two schools of thought on that. In the same thread on B&B, I have seen some folks say they are guaranteed by Spyderco and will be replaced if not flat (see post #9 on that thread; I saw no such guarantee in writing with mine), and other folks (see posts #83 and #84) showing how un-flat they are and claiming that the flatness Spyderco guarantees might not be good enough for straights.

Since I can actually feel some variations on the surface of mine, I was assuming the second opinion must be true, but maybe the stone doesn't need to be so flat for the finishing?
