My local shop has them on sale for $20 which is 50% off.
Can anyone tell me if they are any good for knife making? This particular wheel is 6"x1" grade is "8S"

Thanks,
Alex
 
I use these every now and then. I wouldn't pay $20 or $40
for one, buy 1/4 thick ones for $2 or under - McMaster, MSC etc

Gang them up if you need a wider coverage. Punch out the
center hole to whatever D you need. They don't load, don't grab,
run very cool, very light - thus no vibration .

Don't present sharper metal corners to them, as they will wear out
quickly.
 
The greatest implement for the knifemaker ever devised...I love my scotchbrite wheels. I usually pay about 50 bucks for mine...they are 1" wide. Good stuff.
 
Which grade do you use? They have two left: one 8S and another 7S.
Should I grab them both?

Thanks,
Alex
 
I use one on my 3600 rpm buffer to shape finger guards. A lot of the time I rough it on a 60 grit belt to get the curve started and then use the edge of cut out the cureve which rests against your finger. Works awesome on brass and even if you take it easy on 416 stainless. You can shape your guards outside edges and even hit stag with it to brown it up whwere the white is revealed. Mike
 
:) I've used the same Scotchbrite wheel now for several years. It started as an 8"X1" and is now down to about 6". I use it for a quick finish after grinding to 400 G on the belt grinder. Mine is the super fine grit, but I don't recall what grade it is. The price you mentioned is an excellent price. I'd buy them both at that price.
