A noobs thoughts so far....
I did a light hone job on my vintage Ern. Before the hone It passed the HHT but it was a little sketchy. Now, best I can tell, from reading, it passes all the sharpness tests. I didn't go crazy with the hone, just a few swipes on an 8k and 12k stone followed up with a canvas strop with green paste and then the old leather strop. I tested it on my forearm and it cut through the hair like butter. On to the face. The only thing I have to compare it to is my CJB with Feather pro blades. The Ern seems to have to work a little harder to get through my beard but the end result seems comparable.
I don't know if I will be a daily straight razor shaver. Seems like both my SE's struggle to get my chin and under nose cleanly shaven and cutting though those area's are really rough.
I like the end result my DE gives me but I do enjoy the challenge of the SE. I can see why so many try and give up, it takes patience.
One thing that totally amazes me it how crap cartridge razors ever beat out DE razors. My Edwin Jagger outperforms any cartridge razor I have ever used,
