Are corkscrews verboten now? TSA at SFO found a nice metal corkscrew in my carryon that I thought I'd lost and told me that the corkscrew isn't the problem, but the small (1") foil cutter blade is not allowed.

Never mind that ORD TSA didn't see it/care about it. (to which the SFO lady said, "well, that's Chicago for you")

I didn't want to lose the $20 corkscrew (it has a nice feel) so I checked the bag.
