Need to Lock Your Helmet?

Can't say I've ever felt compelled to lock my helmet up with my bike, but I can see the utility in it (motorcycles often have built-in helmet locks). Just haven't done it. Anyway, Blake, the maker/inventor (?) of this device contacted me below, and . . . why not?

Looks like a handy device. Wouldn't necessarily stop a really motivated helmet/bike thief, but how many really motivated helmet thiefs are there, really? Probably not many (a truly motivated bike thief? If your u-lock isn't good enough, you'll have bigger complaints than the loss of your helmet). Seems like a pretty good idea. Good luck, Blake.

Edit, 8/12/08: So after writing this yesterday I took my bike to the ballgame. Not wanting to leave my road bike parked outside at PacBell/Cingular/AT&T (can we just call it "Giants"?) Park and with a heavy load to carry in to work, I road my mountain bike (and took CalTrain). So I get to the game, but did I really want to bring my helmet with me inside the stadium? Of course not. So there I am thinking about how handy Blake's product would be, mere hours after stating that I don't generally have a need for such a thing. Ironic.

Anyway, it turns out my u-lock was just big enough to fit through my helmet, my frame, and the wide front MTB wheel. So I got away with it. Nonetheless, I would've preferred one of Blake's helmet locks.
