My favorite blades may not be someone else's favorite. However, at this point in time, I like best 1] Feather 2] Super Nacet 3] Shark 4] Astra green in that order. This I arrived at after trying a dozen or more brands of blades.
If any US folks are considering a Henson, Razor Emporium has their 15% off sale, it is the cheapest way to get a new Henson. I highly recommend the Henson razors and buying them through the Razor Emporium deal!
