I ran in to a bit of a problem when trying to flatten my norton 4/8. I purchased a 220 grit wet/dry (different brand than I usually go with). After lapping the hone on both sides I noticed the surface felt a lot smoother. I've completed this process several times with success, but this time the stones feels different, and when i submerged it in water it absorbs very little water. So I put it to the test with a cheaper restoration razor, and teh stone didn't even gererate a slurry on the 4k grit side. Does anyone have any suggestions on how to fix this...would the best bet be to purchase a flattening stone, or is there a simple fix? Thanks in advance.
