So I will be receiving a gem featherweight soon and was wanting any tips anyone can give me. I was told the gem persona single edge blades are good and found a couple on eBay. Is there any place to buy like 100 blades inexpensive. Also are there any other blades besides the gem persona blades that are good so I can try different blades. I saw treet blades but don't know if they are for shaving. I have been told to start with the razor flat on face and barely lift the back. Anything else I need to know or would help me get good shaves from it.
