I have a couple of katanas that I will be dismantling for total cleaning for the first time - are the mekugi re-useable, or should I replace them with new ones? I have new mekugi coming from Sword Armory, so that isn't a problem. Will new mekugi need any fitting, - sanding, etc. or just pressed in for a tight, wedged fitting?..just wondering. Probably a very basic question, but I'm just here, studying at the feet of the Masters. Thanks in advance.
