Just got this w&b 5/8 wedge back together. This blade took every trick I have which isn't many. Put my 1/4 Norton's through the paces. I started trying to set bevel on the 1k struggled so I decided to go right to my 4k. Things turned for the better, after some time on 4k finally got bevel set then 8k and finish on 12k ss. 3 layers of tape and lots of hard times finally got it.
