Actually, MAYBE in second place ahead of the BWM.  Don't get me wrong, I LIKE the BWM but seeing as how it was a gift, I tend to baby it as It is one of my most cherished knives.  Now the Regulator, Well it's my bruiser.  If I need to pry a door open (done that) or just a beater, that is it.  It also was a gift, but it just begs to be used and abused.  Funny thing, no matter what I do with it it just laughs at me.
