I just got a used Wave, and depending on how much sideways pressure I put on the OH blade, I am unable to open it. If I use a *really* light touch, I can usually open it. I can always open it with two hands.
There's a little pin that keeps the blades from opening while the pliers are open. This pin is sticking up just a *smidgen* too far, and if the blade has any pressure forcing it toward that pin, it engages and keeps the blade from opening.
Has anybody seen that before? I figure I'll just attack that pin with some detail files, but I figured I'd run it past y'all first to see if you had any bright ideas.
