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.

And the replica by Hanwei
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.
