The second method is to pass it behind your back out of a Curl. This depends alot on which direction that the devilstick is spinning (CW or CCW). From your right hand, if the devilstick is spinning in a CW rotation, start a curl. Once your hand has come all the way around the turn, and is above the devilstick bring it around your back for the pass to the left hand. This is a difficult trick, and you may want to give the devilstick a toss so your left hand can catch it. Couple of hints: the slower the curl, the easier it will be to pass it, and it might be easier to bend forward a bit when trying the pass.
A very nice version of the second method was done by Jochen Schell on the
'95 IJA videos.
Thanks to Tom Ryan for reminding me to put the trick on these pages.
