I like my recently acquired bm42. When I first got it, I carried it all the time, against my superego's direction since bali carry is illegal in TX. Since the novelty has worn off, I'm usually happier carrying a spyderco police instead.
The bm42 may be cooler, quicker to deploy, and more useful than the police, but it's not exactly low drag -- physically, or legally in most places.
Only one bite so far, and no ER visits.
