It is one of the coolest new swords from the Hanwei forge, and is based on a historical Viking design that currently resides in the Yorkshire Museum and is the best preserved example of a Viking sword currently excavated.
Here is a pic of the actual sword itself which is a hugely popular attraction.
As you can see, the replica by Hanwei is pretty well reproduced, and weighing only 2lbs 7oz and made from 5160 Spring Steel is a truly functional blade that any Viking would be happy to take into battle.
