a while back the good folks at PDW sent me one of their coated 3Wrencho's
at first I was way nervous about removing the fifteen from my tool kit, but I made the leap and I gotta tell you, it's worked out just fine. The 3wrencho is smaller and is long enough to provide good leverage and can serve as an extra tire lever if you need one.
I highly recommend one.
P.S. their packaging is way awesome, like Apple awesome
