Just finished restoring this set today. I had to make a decision to unpin or not and i'm glad i unpinned them. Taking care of the tiny solingen collars was tricky & re pinning was a task.
They are now hygienically clean from top to bottom. They also benefited from the addition of internal washers.
Honed on my Ozuku Karasu , the geometry is perfection and the grind is of the super thin variety . (11/16ths)
The case was disinfected and restored also..
Cheers
