FEATHER FHS-10 RAZOR BLADE

These blades are spineless and are used with the One Blade Razor. Also they will fit some vintage SE razors. Does anybody know which ones the blade is compatible with and have anybody actually used one to shave. Sharp or smooth?

Other than the OneBlade, the Valet Auto Strop is the only razor I know of that can use those blades. I don't know how they shave though as I have never tried either razor. I've seen mixed reviews from OneBlade users and some prefer to use de-spined GEM blades.

I have used the Valet with both the Feather and a clipped SE blade. They are fine, somewhat mild shaving experience.
