Thus it begins in earnest. I have dithered over this project for a year. But tonight I sit to start compiling notes and gathering information. This is an image of a classic viking sword (from this weapon maker). Viking swords are double edged, with deep fuller, they are about 36 (they were shorter early in the viking age and longer later) inches long having a 6 inch hilt, they taper up the length of the blade but more pronounced towards the tip at the end (giving good balance) and weighed 2-4 pounds. Swords were very expensive (in Iceland about 16 milk cows worth). The blades were pattern welded. They could suffer in protracted battles.
