I have had great success with the technique Chris described, specifically with a wooden "wedge". I am quite familiar with that 806 and I would say that it would work fine for splitting with that technique. I base this on the fact that I have done this successfully with knives that I personally consider to be significantly less durable than the BM806 (the BM943, BM310 and Kershaw Ken Onion Leek to name a few). Basically, the way I do it, the knife is used only for carving/creating the wedge tool and for starting the splits.

The 806 is a nice little knife. I prefer something a little more rust resistant than D2 for a survival knive but that it being pretty picky and really isnt relevant.

BM806D2 for those that haven't seen it.
