I have drilled cut and sanded it. It is hard but not unmanageable. I cut it with a heavy duty cutoff wheel on a dremal tool. I used metal bits for drilling it. A little hard to use wood bits but no need for carbide or anything like that. For sanding I used 80 grit cuts like butter and no need to go finer to smooth it out. I made some knife handles with it. Shaped it with 80 grit on a spindle sander and went straight to a buffing wheel to bring the color back. Color goes very dull after sanding but comes right back with a bit of buffing. The dust is very bad stuff if doing any power sanding and creating dust a mask is a must.
