Thiers Issard microchipping
Hello guys.
I consider myself to be an experienced and skill full honer. Been honing for years now.
Resently I bought a TI 69 5/8 razor on the bay. It had a fine condition thou closer examination shoved signs of machine buffering and polishing. I think this is a vital part of the problem.
It took some time setting the edge. There seemed to be a dent in the Center of the edge, left by to much pressure from the buffering process.
Actually the blade had an uneven hollow grind, with suggested that some kind of grinding wheel had been in use.
I set the edge using Naniwa SS 1k, proceeding to 3k, 8k and then finished it on a coticule.
The edge didn't shave arms hairs 5 mm above the skin, but I stropped it anyway. Some blades with hard steel behave the same way. So I thought OK.
After a light stropping the blade worked and took armhair allover the edge.
Shaving test 1 day. Horrible. Pulling and not shaving.
Examination with 22x loop shoved chipping in the edge.
I thought that I made some kind of mistake honing it, so I tried again from the start.
I changed to my Escher from 8k, since it seems to perform better with hard steel.
Shaving test 2. Again horrible. Same problem. Again the loop showed some chipping.
I then tried one more time, checking each step closely with the loop.
Perfect edge. From 8K I finished on my favourite coticule, with slow controlled movement. Again perfect edge. Light stropping. Testing armhairs 5 mm above the skin. Hairs popping allover thou the feeling wasn't as good as my other razors.
Shaving test 3. Horribly again. Pulling and not shaving after just a few strokes.
Examination showed microchipping on the entire edge.
Question.
Does anybody think this blade can be saved?
Is there a way to restore the edge?
I put it in this forum, because it seemed to be the best place.
Yours kindly
Kristian
