a few month ago i found an opinel #10 in very good condition when cleaning out a shed. the only problem is that the blade is very tight in low humidity- currently we have 93% humidity and the timber is swolen that much that i need vice grips to open it... . i intend to dismantle the knife, then slightly sandpaper the slot for the blade and then reassemble it again. has anyone taken an opinel apart and put it back together again or is that not possible?!
