Stuck my Delica in a vice today to tighten the pins. Went a little overboard and now the blade barely opens, and it's impossible to open it with hand. Is there any way to fix this? So far I've tried a combination of WD40, Militec 1, constant opening and closing, torquing, etc. Even tried sticking a screwdriver in between the handle and the blade near the pivot. Tomorrow I will repeat a little more forcefully. And yes, I know warranty is beyond voided by now. I'd buy a new knife before sending a $40 one to be fixed.
