I was given a large piece of pine counter top about 4foot long and consisting of 3 pieces glued together.
I cut it into 3 pieces along the glue lines and after checking with my metal detector and doing a visual check put it through the planer.
And yes you've guessed it I found the head of a cut nail no more than 2 or 3 mil long but big enough to put a very nasty nick in each blade.
I already had a Steve Maskery jig made for sharpening the blades which I use on a regular basis to keep the blades in good order but there was no way a diamond stone was going to take out these nicks.
As I have 3 sets of blades and have now lost my contact for grinding them I decided to experiment.
I placed them in the jig and after cleaning out my bench belt sander I ran the jig over the belt. I constantly checked they were not overheating and kept turning them end for end in case I was putting more pressure on one end than the other.
I removed them 3or 4 times and checked with my micrometer that they were being ground equal until I had removed the offending nicks.
Then using the diamond sharpener put the finishing touches to them.
I am very happy with the results.
