Lion - Super Stainless Double Edge Razor Blades - Pack of 5 Blades

I test drove these like I do any other mid tier blade, in uber agressive razors such as the Fatip Mk1 or the R43. Reasonably smooth and decent sharpness. No nicks or weepers with a nice smooth close shave. I found these to be a tad sharper than Derby Premium and ever so slightly less smooth. Really close to the same shave.
I ran a 2 week course of 6 total shaves with little drop off. Outstanding durability.
