Ever wondered why your mech adjustment screws get smushed? Use a JIS screwdriver not a Phillips one: http://t.co/1vWkbxWKME HT @Rich_KellyIt became clear from the reactions to this little nugget of info that while a few folks went "Duh, everybody knows that!", there were more "I didn't know that!" responses. So obviously everybody doesn't know that.

Since tweets often get lost in the babble of the moment (heck, Twitter is the babble of the moment!) I figure I'd pass this bit of info along in a blog post.
So, to recap, if you have a Japanese derailer (I use Sheldon's spelling for the bit of hardware the Brits call a "mech") you should use a JIS screwdriver to adjust it. In fact, various bits of Japanese hardware in your life may use JIS screws, so its may be worthwhile to invest in a set of JIS screwdrivers.
