Christian, You're right, I did polish the Idun.
I used a DC4 diamond to flatten the surface, then turned the stone to the ceramic side.
I then used wet/dry paper up to 1200p.
After this I used Autosol and finished on a buffer with white polishing wax.
Right now I have carried the Frey at work for a couple of days.
The tip part of the blade is still the factory edge after about 4 years in my inventory.
This edge quickly rolled and microchipped, after a light contact with a concrete wall.
I reset the edge with the DC4 diamond side and so far no more edge failure.
There's still a tiny microchip left to grind away, but I will let it disappear as time goes by.
The Idun hasn't behaved like this at all and I have used the Idun very hard for 6 month at work.
The Frey is very nice to work with and I expect it to perform as well as the Idun, when the factory edge is all gone.
Regards
Mikael
