Hi I'm wondering how I know when my razor is ready to move from the 4k to the 8k. I can shave the hair off my arm dry fairly easily and then I spend some time on the 8k. I still can't get it to pass the hht, but almost. Then I go strop about 30 to 40 times. Lather up and try shaving and it still pulls and isn't that comfortable. I'm asking because I have seen people and have been told that you should be shave ready with a 4k and 8k combo stone and I've seen people use it that seem like their razor is sharper than hell and cuts right through. I believe my facial hair is pretty course but still don't believe that should be a factor. I'm craving a good shave and am very anxious. Can anybody help me out please?
