I was watching the science channel last night. Their show "how it's made" came on an I see a straight. Naturally it caught my attention. They went through the fast an dirty way dovo makes them. Not really in depth but showed the basic steps. The part that interested me the most was how insanely fast the lady honing an stropping the new blades was. Now yes I know they are not up to our standards, but still very impressive. An yes they do the hanging hair test to check. Cool little inside look at the dovo plant.
