I don't know anything about edges.
I wanted a really smooth shave today, so I used the only Straight I have that I know was finished on a Coticule. The shave went great and it was really smooth. While I was cleaning my razor I thought "I need to learn how to use a Coticule. That was a good shave". I went to my Straight Razor Journal to mark down that I used that razor and found out I touched it up with a Naniwa SS 10k and 12k over a month ago! :rofl2: I've got a lot to learn!!!

You'll find that as you get older, each day becomes a new adventure!
Even if its the same as yesterday!
