Astra Superior Stainless Razor Blades
Tried a few different razors as I go through quite a lot, use them to shave my head everyday, usually find that 1 and a half blades( I have a razor that needs 3 halves) will last me 5/7 days of everyday use, so basically 30p/50p a week for razors isn't to bad of a price if you ask me, and I found this particularly one to be the closest shave
