I have a number of razors, but I generally only shave with one. Most of my facial hair is very coarse, so even with a shower and a good soaking, it still takes its toll on the edge. I have a few fine hairs below my bottom lip, and I can tell my edge is going when it fails to cut these hairs. That's usually about 15-20 shaves. I've started stropping with CrOx every few shaves to try to extend the time between touch ups on the hone. I haven't been doing it enough to notice a difference yet.
