Thanks everyone!
Andrew, Because you have shot the Boneheads into sand repeatedly, they've likely become very dull, which is really no big deal but as mentioned above you'll need to start with the coarsest abrasive you have access to. Step one is to work only the bevel side till you can both see and feel a light burr running continuously from tip to heel. Don't leave the coarsest grit till you've raised the burr. Then continuing to work only the bevel side, progress through your finer stones. Then when the bevel is thoroughly polished, flip the clamp and using strictly forward passes, do the absolute minimum necessary to remove the burr from the unbeveled side. Then finish up with just a few more forward passes alternating between the beveled and unbeveled sides of the blade.
The angle you'll be sharpening at will be slightly higher than the factory bevel. So as you pointed out, you'll only be working the very cutting edge. That's exactly how it's supposed to work. If you need help, give me a call. I'll walk you through doing one on the phone and it won't take 10 minutes, even with me stopping to explain the how and why of each step. BTW, It's really personal choice but I think you have the right tool for the job. While the knife sharpener can perfectly duplicate the factory bevel angle, the BHD sharpener is much faster and you'll be able to do 2 or 3 heads in the time you could do 1 with the knife sharpener. Thanks,
Ron
