First Restoration, Family Heirloom - need lots of advice!

[MattCastle]

I'm looking for some opinions on the blade and potential for this razor.

My girlfriend recently found a family heirloom - an old Ern straight razor. As I am the only person she knows that uses a straight razor, the job of restoring it has fallen to me - not that I'm complaining! I haven't actually seen the razor in person, but I think it looks promising.

I was hoping somebody could give some history on Ern razors, there wasn't much on the internet. Are they good razors?

After reading around the forums, my plan so far is to clean up the blade with some sandpapers, working my way up the grits. Some suggestions for what grits to start with and how long to use each one would be much appreciated. The edge looks decent to me so I was thinking some effort on the 4000 and then some pyramid patterns with the 4000/8000 and it might be workable. Am I heading in the right direction?

Thanks so much, this forum is a godsend
