Ive got a few edc's that are fine (two in 420, two in 154cm, and two in d-2 from ag russell), but I have a new one in 154cm (allready have two in this steel that are fine) that has lateral blade play. I tried to tighten the pivot, but the play is still bad. I noticed that the back spacer is keeping it from getting tighter so it looks like my problem is the nylatron (if it is nylatron, or some other plastic) washers! kind of discouraging having this on a new knife!!! I havent even cut enough with it yet!!!
