I have a 30x loupe ordered but I have been just using bright light and looking close to assess the edge for now. And when I meant I was having trouble with my razors lately with them tugging when I shave test, I meant lately it's been with all of them. I have an old boker, a torrey and some GD's. And for testing I have been popping hairs from my belly because my arm hair is too thin to matter. I think I have been having trouble because lately I have been trying new methods lately.
I just went back to my beginning method of using more pressure until finishing and my Wolff Lane Boker is passing the hanging hair test to where it cuts thru a thin hair far from my thumb. I guess I should do what I feel is right in the long run.
