I had a barber shave in New Orleans some years back and was so impressed two days later with the lack of regrowth that I went back and bought some supplies to try and duplicate it.
I did try straight razor shaving under Willie's guidance a while back, but could not get comfortable with it, nor abstain from nicking myself. I agree with Willie that it's ridiculous we cannot seem to get back into what was an almost daily activity for men just a generation or two ago.
From that visit to Aiden Gill For Men barber shop in New Orleans, I did get into using products from Truefitt & Hill, a London barber shop that's been in business since the 18th century. I cannot afford to use their products daily, but I do on Sunday mornings and on special occasions.
I like their Grafton Shave Cream and After Shave Lotion. Subtle scent, manly, not overpowering. They offer several others.
I pre-treat my face with witch hazel oil or lemon oil.
I agree with Willie re' a cold water blade rinse. It has to do with contraction vs expansion of metal.
BTW; I shave with a three blade razor from Dollar A Day Shave Club and I've got dozens of good Robeson razors from which to choose.
