I get my haircut in Tribeca and a pretty great barbershop. They do a great job and are very affordable.
This last time, they cleaned up my cut with a shavette with Dorco blades. I told the barber there are better blades out there.
I am going to PIF him today Gillette green (permasharp), black, feather, shark, astra, derby, and a Personna Red.
I will also give him the addy of Pasteurs so if he likes any of them he can pick some up.
I did the same for my barber. I gave him a pack of Feathers and 7 o'clock yellows. He's already a DE guy, but now he's shaving with the yellows at home!
