This is an excerpt from The San Francisco Chronicle editorial page:

"Kryptonite may be able to fell the man of steel, but apparently it's no mightier than a pen when it comes to protecting bicycles. A San Francisco bicyclist touched off a national furor recently when he announced that a few versions of the famed U-shaped Kryptonite locks could be picked by using a simple pen. He came upon his discovery after his very expensive bike was stolen and a friend mentioned that the tubular cylinders in some of the bike locks could be opened with the flick( and a few turns) of a cheap Bic. His internet warning has been visited by more than 300,000 concerned cyclists from here to Metropolis, who are spinning over the news.The Massachusetts bike-lockmaker has been in full damage control mode since last week, when it announced free upgrades and rebates to customers (depending on when they purchased the affected devices) and a recall of seven versions of the lock. It's probably only a matter of time before lawyers start passing around their business cards at local bike shops. Kryptonite goes by the slogan "tough world, tough lock." At least it's right about the first point. And the tough guys are packing Bics."
