I've watched it. Did you notice him hitting the ground with it? Even INFI will chip hitting stuff like that (rocks and steel). That one video means nothing but how not to use a knife. This RD-9 is FULLY CONVEXED to a ZERO EDGE and doesn't chip. Some guys says he sees chips in the blade ........ where? http://www.youtube.com/watch?v=2aEPXhDkqLQ
Without pointing to specific knife brands or models (I already offered a suggestion above) for splitting you want a blade with a thick spine. But you probably already realize that.
So any knife with:
1. Suitable length to leave enough tip extened to get good contact with the baton. (length is really dependant on how large a slice you want to take off)
2. Good enough steel (heat treat etc, etc) to withstand the abuse.
3. A good thick spine to provide the "splitting wedge" effect.
Just curious, have you tried batoning with your axe? That is another option worthy of consideration.
