DanaM:
Can't argue with you on that eddie, we agree to disagree all the time ;D

Mullet, I learned the sharpenning technique from Steve Allelie. Dont know why it seems to sharpen better but I think it has to do with the softness of the antler. The antler tends to crumble on its edges and takes of micro flakes when knapping. (?) I think the edge is not crushed as much when using the antler in the final sharpenning stages as copper would. To me though it just seem really sharp!  ;D

David, the ABO percussion tools are nice for obsidian because the super hard tools can put to much energy into the rock and work like a rock crusher.  As for pressure tools, I don't think it matters.  If you are finishing the edge, a nice sharp metal tool is about as nice as anything.  You remove all the rock that the tool touches anyway, so it cant really dull the edge.  Justin

Coo-wah-chobee:
   Whose Steve Allelie ? Copper has the same consistency as fresh antler so it works the same on pressure flakin and ifn ya doin it correctly it dont crush the edge. ;)...bob

D. Tiller:
Hmmm! Not sure about that Justin but will take a look into it.  Just seems that when I chip out a small arrowhead they do come out sharper with antler tines than with Copper.
