I usually carry my Seb, and my BAD. I just picked up a GL BAD from Trevor, so I cant wait for that BAD boy to get here! I like the Seb for convienence, but when its a really tough cutting task ( hard plastic, steak on a ceramic plate, anything where S30V likes to roll/chip) I always have my BAD there to laugh it off. I have to say that INFI stay sharper, and as thin as the BAD is, it slices just as well as the hollow ground Seb.
I am lucky to also live in a state that doesnt discriminate against knife folk, so I am legally allowed to carry any size fixed blade I want (I'll have to try the FBM one day). I like having a folder on me, and depending if I am working that day or not, I'll throw the BAD on the hip. If its not on the hip, its in the side pocket of my bag.
I always keep a SASH1 in my bag, and have the utmost confidence in its ability to help in any emergency situation.
