Pattern Welding Explained as Wearable Art


Pattern-Welding was used throughout the Viking-age to imbue swords with intricate patterns that were associated with mystical qualities. This visualization shows the pattern progression in a twisted road with increasing removal of material. It took me two years of intermittent work to get to this image. I liked this image so much that I ordered it for myself as a t-shirt and am looking forward for people asking me what the image is all about. If you want to get a t-shirt yourself, you can order this design via RedBubble. If you end up ordering a t-shirt, let me know if it ends up getting you into any interesting conversations!

Forging a Wolf Tooth Spear



A Spear Born of Fire is a new video series in which I will show how to forge a Wolf Tooth Spear. The spear closely follows the famous Finnish spearhead from Rovaniemi, Marikkovaara. It will have two pattern-welded bars within the wolf tooth pattern. I will start at the very beginning by consolidating wrought iron that will then be forged into a wide plate. Afterwards, I form the spear socket and continue with lots of forge welding.

Early Experiments in Visualizing Pattern-Development for Viking-age Blades

Visualizing pattern-welded steel has always been intriguing to me. At the forge, I end up layering different kinds of steels by varying carbon-content, nickel or phosphorous but ultimately don't know how the patterns will look until everything is forged, heat-treated, polished and etched. Using tools from the visual-effects industry, to be specific SideFX's Houdini, I have started exploring different ways of visualizing pattern-development. Here is a very early experiment:

My Most Complex Pattern-Welded Sword



A Day at the Forge documents a single day at the shop. This time, I am working on a complex pattern-welded sword that contains a core of 8 pattern-welded bars. Watch me forge-weld the core and then assemble the cutting edges to create the pre-form of what will become a majestic Viking-age inspired sword.
