Three blade heads are pretty easy to sharpen, because the angle is already set acrosstwo of the blades. There are some diamond stones made by DTIwith whichI have had very good results - they come in coarse, medium, fine and extra fine. I think G5 also makes a diamond stone for broadhead sharpening. I woud highly recommend these over a regular arkansas type whetstone.
Good info I was wondering this myself. How about a two blade stinger? Any double type stones or do you have to do one edge at a time?
And "whetstone". You are good. Spelling.
