In many ways this is an interesting video. It shows some modern expert blacksmiths making Legend of Zelda’s Master Sword. This is Link’s Master Sword. It is just a recreation of course but the sword itself is just cut from a sheet of steel. Does that mean it’s weak? Not at all; watch to end to see how it destroys stuff.
It’s also interesting because we discover how the process could kill you. It’s not the weapon that’s dangerous but the technique used to create the huge cross-guard the sword uses.
If you fancy something like this for yourself but don’t have a master swordsmith handy then fantasy swords made real may well be the post for you.
