My Razors won't keep an edge
I have a DOVO bismark and a Lee magnetic and sent both of them out to get sharpened. They came back fantastic thanks to a member of this forum. But after a couple of shaves both razors have lost that extremely keen edge. I have a DOVO hanging strop that I have conditioned with Fromm strop dressing and I've put yellow strop paste on it a few months ago. I strop my razors about 50x before a shave and I don't use the same razor 2 days in a row. What am I doing wrong? I do have a very thick beard, barbers have commented on the difficulty in shaving my beard. Do I need a different razor, strop paste, etc. I've only been doing this for about 10 months and still consider myself new to it. Thanks
