Bazzle dissed the Viel chisel sharpening attachment and suggested I start a chisel thread. Here it is. I cannot freehand a chisel, it gets convex. I use a little wheeled gizmo that rolls on the stone and let's you set the angle. I like it but if the chisel is too short you cannot set a 25 degree angle.

So, Bazzle and others, what do you like?
 
I do most chisels on the Tormek. Freehand you could try the sideways deal with the edge of the chisel pointing toward the side of the stone. Works pretty well. When the tool becomes to short to sharpen effectively its time for a new one. Unfortunately.
 
I freehand them on hard waterstones. A little convex doesn't hurt anything, you will always have a little convex with hand sharpening.
 
if you can cut wood into a triangle/wedge shape you can sharpen pretty much anything
attaching the blade to the wedge not required but you're already used to it so :)

this one doesn't touch the stone BrentBeach/Sharpen/jigslant

this one rides on the stone, its a wedge clamp, you can clad with tin for longer life

Brent beach has a good widget he uses, and Lee Valley among others make roller guides that will work reasonably well. I freehand mine and have gotten to the point where the cutting edge stays dead straight. There is still slight convex from shoulder to edge, but the important thing is that it not be smiley shaped across (unless done intentionally). Even on powered units, without a rock solid guide there is liable to be some shifting.
