Does anyone use the Dremel Tool lawnmower blade sharpening attachment ?. I saw one at HD for around $ 9.00. Seems like it would work ok ,but may be slow. If anyone has any favorable opinions on it I may go get one. 

Thanks for all the opinions. I think I will buy a small  4.5 inch hand grinder to use. I have a bench grinder that I have used before to sharpen my blades, but like some of you said it is hard keep a proper angle. That is the reason I wanted to maybe use a Dremel because it always keeps the correct angle. Is  there some type of attachment you can use with a hand grinder to keep the same angle ?. What grit grinding disc do most of you use ?.
