A gentleman donated 240 Feather FHS-10 blades to B & B's Great Blade Exchange. I am told these blades work in the Oneblade razors, as well as some other SE razors. I don't know if many are aware of the GBE here in the SE forums, but there are a few SE blades available, & now there are Feather FHS-10 blades available in the GBE, too! Check out the link at the bottom in my signature to learn more about the Great Blade Exchange & how you can participate. Enjoy your shaves!
