Answer Question
Hapstone vs Poltava
How do these compare to the Poltava Premium Metallic CBN Stone 6" x 1"? I know the the thickness are different. Does Hapstone or Poltava cbn stones have any advantages over the other? Is the metallic binder used the same for each brand? Since both Hapstone and Poltava Metallic cbn stones are made in Ukraine it almost seems that they might possibly be exactly the same?
Thanks!
