Did you ever come across a blade that just doesn't take an edge? I just picked up a couple of ebay specials, one of them is a neat looking "Vedepasco" 4/8, Solingen made, silver steel; I'd have thought it'd take a neat edge, but it just won't approach shave sharp.

I've honed up a handful of other razors but this one has me dumbfounded. Have you ever seen anything like this (apart from a chinese/paki cheapo razor)? Ever manage to overcome it?
