I find I get 3-4 good minutes of shavings at a stroke every 5-8

seconds, and then I need to advance the blade just a fraction to keep shaving.

I pulled the blade tonight and it will no longer shave arm hairs.

Definitely has dulled, but I will try again after I rehone the blade and when I advance it the second time I will remove the blade to test again.


  • + + Yes, many hard woods (not "hardwoods") will dull an edge fairly quickly. Try wengé or panga panga and you will express stand time not in minutes, but in strokes.

Advancing a blade will work because a plane will work reasonably well with even a somewhat dull edge. PvR

  • + + I suggest you look at your shavings. These will look different, too. PvR

PVR states:

According to William Lincoln, it exudes a gummy residue if heated by dull tools. Might be messy. I've always made sure tools for purpleheart are especially sharp. While teredo (shipworm) is not a particular problem outside oceans (docks, ships, boats, similar structures), powder post beetle can chew up the sapwood.

  • + + That is possible, but only if the relevant tree was damaged during its life. It is not the rule.

  • + + Sapwood is never resistant to anything, no matter what wood you are talking about ... PvR
