The upper piece is what I consider a more traditional cut and is quite beautiful, however the lower cut is just as beautiful and more off the beaten track. While both are beautiful in their own right, they will be part of a greater whole once integrated part of a knife. Most of the time, I match the grips to the blade I'm making, but given either of these blocks, I would build a knife around the grip material. Given the choice, I'd go with the lower one because it is different.
