This should be the definitive list of all speedi-sleeves. There may be other manufacturers, but I believe they all cross to SKF numbers. I'm not sure what you mean by a "sharp" versus a "rolled" edge. They always have one tapered edge that can slide past a seal without catching on it. They also all have a driving flange that is "rolled", if you will, up away from the shaft. On the stock industrial numbers the flange has a groove cut around it so you can tear it off if need be (rarely necessary), although I've seen some lower-priced special-purpose ones (common automotive applications) where you can't tear off the driving flange.
If you're looking at a sleeve that has a "smooth" edge that's still so sharp that the seal will catch on it, I don't know what you have. Since the whole point of sleeves is to make a good surface for a seal to run on, it wouldn't do any good if you couldn't slip it past the seal without damage. If for some reason you absolutely have to use one that has too sharp of an edge, wrap some very thin shim stock or copper sheet around the shaft to cover the sharp edge of the seal. Start it out somewhat conical past the end of the shaft so you can get it in past the seal without damage. Then make it more cylindrical as you push the shaft the rest of the way in, until the seal is past where the sharp edge of the sleeve is (protected by the shim stock), then pull the shim stock out.
