Princeton Wongwrote a review of Park Tool I-Beam Mini w/ Chain Tool - IB-3 on December 23, 2008
So the integrated tire lever turns out to be a piece of junk. Used it for the second time just recently while home for the holidays and both ends snapped off while trying to mount a new tire. Expected much greater durability from a Park tool product.
Also, the plastic dovetail mount on the lever spreads a bit from use so it no longer stays put on the tool. This was the only thing keeping the loose bits from jabbing your hands during use.
