You know I have a little saying that I think covers this controversy pretty well:
"every thing is easy if you know how to do it"
As in sharpening a drill bit, well I have sharpened a fair number by hand, and find it a difficult time consuming thing to do, especially for smaller bits. Now I have no doubt that some guys find sharpening drill bits with a grinder an easy simple rewarding thing to do. I do not own a Drill Doctor, as the price has put me off from owning one. But I have no doubt that it is a good tool especially for the difficult smaller bits. I would be willing to bet that there are things I can do pretty easily (like programing old Nortel Meridian PBX's with Command line interface) that others find very difficult. But I also know that the fact I have been doing that for over 30 years makes a difficult task for most, an easy task for me. So to sum up what I am trying to say is just because something seems easy because you have been doing it for a lifetime, does not mean it is easy for anyone to take it up and get the same results. That's all. Merry Christmas everyone!
