Rex,
Gene Beal and I cut a large block of Lignum Vitae this past week. (In my spare time) It took 45 minutes and lubrication to the large carbide bandsaw blade to get it done! Gene purchased this bandsaw recently from Italy (Hi Guido). It has a 5 HP motor! It was "still" a chore!
Great knife and incredible wood! Best of luck with it.
