Thanks everybody.  I know the top one is bocote, and the bottom one is cocobola, but i'm not certain what the middle one is.  It came from a lot of hardwood scraps i got from the big auction site a while back.  Pat, they're a really easy way to try out a couple of knives.  If you want I've got one already annealed that I can bring next weekend.  I've got a couple of bars of 1084 I can't wait to get pounding on, so hopefully I'll have something a little different to show soon.
