Hey Bob
  Its bone. So its harder than most wood, but softer than nearly any metal.
Think maybe soft aluminum. Any metalworking tool works a treat.
So sure, eggbeater with a twist bit.
  Hacksaw.
File, either coarse or fine.  easy peasy

  Warning, if you sand or grind bone with a powered device, well nobody 
needs to tell you its dangerous.
One whiff and you are out the door on your own! 
peeeeeeeeeeeeeeeeeyuuuuuuuw!! haahah

  Use powerful air control. I wouldn't even trust a respirator on this 
one. I want exhaust.   :)
   yours scott
