Most impressed with the guy that won with his version of the Viking Battle Axe he used the most basic of forges a pan with a hair dryer stuck on a tube the result was probable not far from an original one rustic looking even the handle was hand carved all done in his garden.
Very inspiring makes me want to have a go at it sometime it looks possible to put a similar forge together with small change.
I suspect his most expensive tools were the anvil & hammers.
