I need some advice from the great people/ experts here. i have a tech from 1965 and a NEW SC. I'm looking for a vintage closed comb razor that is a little more aggressive cutting than a tech. That is; cuts a little better but is still smooth on the face. To me aggression does not mean rough. The hair at the corners of my lips and chin are thick and twisty and at the corners very hard to remove without many passes and irritation. The NEW is great but doesn't quite do the job and I don't wan't a zamack head - I've had several screw break. Your suggestions are welcome
