Picked these up at a local Loblaws (Canucks will know what I'm talking about, at least the ones in Ontario will). Nice blades, I would put them at about Derby sharpness but not (for me) Derby irritation. Still, at $0.45 per blade, they might be a bit pricey for some of the members here. :rofl As far as I can tell, they are probably made by the American Safety Razor Company. The retail package doesn't say much beyond "Made in United States", but the blade container is very similar to what they show on their website for their WWII blades.
