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:

A reconstruction of the Wolf's Tooth Spear

Here is the first successful experiment in recreating the famous Finnish lance. The core of the spear consists of wrought iron which have been forge-welded to the spear socket. Twisted pattern-welded bar has then been attached to the core in another forge-welding pass. Finally, the outer higher-carbon steel has been prepared with a wolf's tooth pattern and then also attached via forge welding. Expect a video documenting the whole process.
