i highly recommend that you do a shop clean out before the season
begins....
if there's that much dust... that is...
just think ....you'll find all kinds of cool stuff

==========================================
i mentioned the upside down belt sander
as the cheapest way to go...
and not necessarily the best solution...
i would think

however, that the finer the grit of sand paper
on the belt sander, the less friction ,and the least amount of heat
to touch up a chisel edge
might be a compromise.
