Today at work I started to remove some large chunks of wood off of a mulch BioBed that we just replaced.  They looked bad on top of the mulch and we have a tour coming through tomorrow.  I grabbed the biggest piece and tossed it in the golf cart.  That's when I noticed it was spalted.  The chunk is 14"-16" across and about the same in length.  I cut both ends off to get a better look.  I don't know what type of tree its from.  Maybe Maple??   I think its solid enough for knife handles.  I'm not sure if it would work for turning on a lathe.  
If I was to cut this into knife scale blanks what would be the best way to make the cuts to get the best looking pieces?
