Swedish iron is what was imported it was and is very pure and was already in bars that had strick quallity controls, the steel was made in Sheffield due to water power and lots of coal. also the eventual use of cast/crucible steel and then bessemer

Im sure had Napoleon and the chaos of revolution in france and europe not put serious restraints on Solingen. there would be lots of old German razors out there too history/geography/maybe culture just had other ideas

I geuss Im bias towards the Sheffields but any razor from Germany in there day is usally a winner and comes from a time when the razor was at its final pehaps perfected form full hollow, they are usally out of my price range at least the ones I want aka Puma
