There are no brackets or anything like that. It is all free hand so there could be a small learning curve for someone who can't chew bubble gum and walk at the same time but it is very quickly overcome. The secret is to just start out with very light pressure and practice on an old junk blade or broadhead and get the feel of it. Once you have accomplished the wire edge with the carbide wheel, then go over to the polishing wheel and 4 or 5 strokes with that, you'll be hair popping sharp. Sure beats spending a bunch of time sitting there with a small round file taking strokes at it. I guess I made it look fairly easy on the video but that literally is how easy it is. Once you've sharpened a few things with these wheels, you'll wonder what you did without them for all these years.
