The A&A is pricey because it is hand worked and tempered, and it is durable. Also, remember that the blade profile of the Shifford Viking was for use against opponents wearing skins, padding, leather, or the occasional item of iron, like mail or a helmet. If you want to cut up metal sheet, you're looking at the wrong blade profile. If you are going to hit sword on sword (whih i do not recommend) you are looking at the wrong blade profile.
In another comparison, you don't get an axe to stab with, you don't get a spear with the intent to chop.
A&A will also make a viking with the right type of edge for stage combat, that is, blade on blade contact. Nothing chews a sword up quicker than that, and I consider that to be abuse.
