>>10437776The rase is a smoother glass file with divots in it like a golf ball or something right. The divots act like the 220 and the smoother glass acts more like a 2000. Its different thannthe typical file you would see with the lines //////\\\\\ kind, like most nail files youd find or a metal file will have. The edges have an angled bevel too so they dont dig in as bad.
Most the time I will clip, cut the nub down to about as thin as a card, then file with the raser and rub my thumbnail over the white spot left over, repeat with the file if it feels raised or doesn't go away, run thumbnail again and wipe it off. Maybe hit it with the buffer to polish it. Theyre good for lazy builders and that pisses some people off.
