what do you guys think would be the best lube for a leatherman charge tti? i dropped it in a pile of thinset from some open bags....dont ask.....and ive got it very clean with wd40. Its actually almost like new again, however some of the tools dont open as smoothly as new. Im pretty certain theres no thinset in the joints as i cant hear any grinding of scratching or anything anymore. Just wondering what everyone else uses on their leathermans.
