my razor seems quite dull, doesn't even shave off hair when i tested on my leg. the last time i used it, which was maybe a month ago, it seemed all right. my razor came pre-honed. so my question is what sort of stones will i need to get back its original sharpness? 1k, 4k, 8k, ... so on? what are some good whetstones? i am in japan, fukuoka. if anybody knows some place where i can get it honed, preferably in fukuoka, but even if i can send it off somewhere in japan that would be fine. i have never honed myself and am afraid to damage my razor from lack of knowledge/experience, so a better option for me would be to get a pro to do it.
thanks.
