Power Tool Sharpener ????

Hey all,
I stumbled on this website and sharpener :

Check out the video.
I am curious if any one has tried this and/or what you think ? ( even if you havent)

It looks kinda useful.

I have been told good and bad things. Good: it works great and sharpns the most damaged chisels nicely. Bad: its fast! You do some serious damage quickly if you are not very careful.

Yeah, what Aloha said rings true. I've been watching this tool for awhile since it emerged about a year or so ago. They have added a lot of accessories to squeeze a few more bucks outta you. The main issue , like Tom says is it's too fast and you an burn a chisel in no time. m
To use this tool you need a good grasp of how to sharpen a chisel manually so you will understand about the burning or blueing of the edges, once that edge gets a blue spot on it it's hard to bring it back and most chisels aren't hardened the full length of the tool. So Learn first then play.

Thanks for the feedback.

I guess it would be useful for cheap flat chisels,
or other tools,knives,etc.
