I too like band saw blades, 3/8 – ¾. I do not roll the edge, just keep them square. Use a good FLAT stone, diamond is great. Stone the flats and the edges, on the ¾ I do the ends too, keep it square to the stone, for the edges I use a piece of hard wood with the blade clamped against it. Do all sides and repeat. Try a hook too and see what you think.
Glass works well too, I prefer broken rather than cut, fewer scratches.
