I enjoyed this video immensely. Tord of Thor’s Forge in Sweden shows a process of making a two-handed Dane Axe blade the traditional way – from recycled wrought iron and carbon steel, both refined by bending and forge-welding. As close to a Viking-era technology as possible.
I learned a lot just by watching and I hope that some day I will have a chance to try out some of those things myself.
Video is 40 minutes long and there is about 4 min introduction by Matt Easton. Take that into account if you decide to watch.
