The cheesegrater was a staple of all of our toolboxes some years ago when most bodyfillers were harder to sand. It also was popular (and probably the main reason it was used) with collision guys who had to get stuff done fast. Cave and pave. Apply the filler thick over the dents,sometimes even not working them out, cheesegrate it, hand sand the cheesegrate marks (if you didn't you had terrible pinholes later) then reapply filler.Just a tool to speed up and abuse the process.
If you are working your dents out correctly there is no need for a cheesegrater.
