In response to Joel Hull's sharpening article in Issue 19 (page 46), a subscriber writes:
'Joel Hull's article on sharpening was also outstanding. Joel have you ever tried the new 3M sandpaper? The grits are measured in microns - from 1.5 down to .5. Sounds like over-kill, but I find them very easy to use with excellent results - and they are inexpensive - $2.50 a sheet. Thought I'd throw the gauntlet down and see if any other reader has tried the 3M paper.'
