I got up this morning and as usual I used an old Norelco electric shaver that my father gave me, I have an old Gillette super speed and have been trying to use it but the blades seem to be dull right out of the package, I bought some blades on the Internet called "Topaz" I think they're made in Pakistan or India, anyway the first blade out just about pulled the hair out instead of cutting it, I am new to shaving with a double-edged razor, I was wondering if anybody could give me advice on which blades I could try. Thanks
