I'm glad it works because I know there are a lot of woodworkers out there that are always willing to spend a lot of money hoping the marketing ploy really does do all it says it will do. In that case, I hate to see anyone get ripped off.
Still I am kind of biased about this machine. This is my opinion, and my opinion alone, and not meant to detract from your post here, but its the whole principal that will keep me from buying one of these machines.
To me, the Scary sharp method was an excellent tool sharpening method. The ultimate method really. It was simple, inexpensive, fast and produced great results. It did all that with nothing more than a piece of glass, sand paper, and fixture for holding the cutting edge or tool. It was a cheap-skates way of sticking it to the man, the man being the big companies that try to market and ploy ten thousand different expensive ways of getting the same sharp edge on a tool.
I knew it was only a matter of time before some company came out with a gizmo that used the glass on sandpaper method, but with a big accompanying price tag. I did not have to wait long. Here it is I guess. The first of many more to come.
As I said, I am glad it really works, because far to many of these gizmo's don't work, and really just pull hard earned money away from good woodworkers. Myself, I'll stick it to the man in my old fashioned sharpening way. It just works for me.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
