I have the Ridgid two blade planer, no issues with it.  I recently got some exotic wood, red marble wood to be specific, and planed it down to make a chess board.   This wood seemed to kill my blades pretty quickly.  It also killed my band saw blade but that one has been in use for a while and not unexpected.

So should I just keep getting HSS blades or are there carbide blades that have a longer life?  I think the spiral head is out of the question due to cost.  Any recommendations for blades?

Thanks, Tom
