Any of you ever use the little slide through sharpener three rivers sells for three blades like woodsman's?

Tried to copy the link, but my iPhone is contrary.

If you are sharpening a Snuffer, VPA , Wensel or most any 3 on 1 broadhead for that money you can get yourself a 3 sided jewel stick. You will not find a better tool to sharpen a 3 blade. I am shooting VPA 175 grainers and I can get them so sharp in just a few strokes on each side that they will make your eyes bleed looking at them. I have never had luck with the type you you refer too, they sharpen but no where near as sharp as I like my heads! Shawn

Many ways to skin this cat.  Shawn is likely onto something that should be pursued as scary sharp is never a bad thing.  I have really good success with laying them flat on a diamond hone and then stropping on cardboard.  

If you do not have a diamond hone wet/dry sand paper on a piece of glass or tile works really well too.  

There is also the hollow ground method that puts a ridiculous edge on Snuff and Woodsmans using wet/dry over a piece of PVC pipe.  It is a bit of work establishing the hollow edge but once you have it touch ups are easy with the apparatus.
