have a full size 880 B/S tanto, its a pretty good knife, imho would be as good for SD as anything mentioned, really, but the mini is too small for my tastes, a good knife though.
a few points to consider:
*the B/S is a LOT thicker than, say a emerson CQC7, has a longer blade/thicker blade/wider blade but in a MUCH thicker package. i have a BM 975S-BT, the 4" CQC7, and the B/S blade is about the same length, a little wider, and a lot thicker. the B/S is similar to a strider GB folder, but only a little. the handle shape is really a lot diff imho. if ya want a strider folder save up and get one, imho, while being a great knife the B/S aint a strider.
*the B/S doesnt carry real well imho in a pocket, its ok but a lot thicker than say a EKI CQC, etc, and the G10 is rough, and i am talking about jeans, w/nice pants ya would have to go IWB imho. also pretty heavy, and the G10 is hard on pants.
*imho the B/S is more intended for heavy duty outdoor use, where concealment isnt a priority, but heavy duty construction is. i would think they are more at home in the pocket of BDU's, or in a hunters pocket, than downtown in a nice set of pants w/a suit. but of course thats just me, lol. i usually carry mine while biking in a kydex belt clip sheath, myself.
good luck
