I just won this razor on the bay. Is this a razor I can use everyday or only with 2-3 days growth? I use astra sps. My beard is heavier thn normal and i have a sensitive face. Would this razor shave me in 2 passes? I know angle will be imperative with an oc, but are there any other tips for my 1st shave with it? Also what about problem areas like below lip area and neck?
