The heel of each blade had an annoying bulge at the bottom of the plunge grind, so I decided to add a small sharpening choil. See before and after pic below. This was done at 15,000 RPM on a variable speed Dremel using a 150 grit chainsaw sharpening bit. I have since added choils to a couple Spyderco knives in the same way. Makes sharpening these knives so much easier on a Wicked Edge. Just thought I'd share.
