They made the older 32 and 36 tooth 1/2" ratchets with hard handles. I haven't seen a factory produced 80 tooth, though.
I don't think its too hard to remove one of the soft grips and fit a new hard handle. If I remember right the handle on my s836 is closest in size to the sdd6 screwdriver handle. Like Hpozzuoli said, you may have to drill out the new handle to the correct diameter hole and check the depth to be sure its deep enough to fit.
