The kind on a stand. With an 80 grit belt. It seems to do the trick and keeps the blades even.
Just curious... How wide is your belt? I see industrial ones that have a 4" to 6" wide sanding belt on them. Actually that's a pretty neat deal. Just take the blade and hold it at the right angle, using the platform i assume, and push it against the belt. In 10 seconds pull it off and chack it, if it's not done just repeat. The whole cutting edge would get the same amount removed all the way across.
I guess the catch is that good belt sanders cost as much as some blade grinders!
I still use my angle grinder and get along fine...
The corser the grit the faster you can sharpen. The faster it gets done the less heat. My dealer/mechanic shop has a blade grinder. I noticed one day how razor sharp and perfect a set of customers blades were that were sitting on the counter. The guy said that they switched to the corsest wheel and get better results that way.
