Anyone with $50 to blow can go online and find a cheap metal replica of Link's iconic Master Sword from the Legend of Zelda franchise - but what if you want a quality replica?
For that, you'll need to spend a good bit more and find a talented blacksmith.
While money might not be an issue for some, finding a skilled blacksmith willing to take on a commission is far from an easy task. You could take a quick Google, beg Siri for help, or wander around a larger renaissance festival to ask advice, but the absolute best place to turn for something like this is to the ever-talented Man At Arms.
After bringing the world a replica of Sora's Keyblade, Cloud's Buster Sword, and Finn's golden sword, AWE me's talented forger took hammer to anvil to create a functional, metal version of The Master Sword. The results, as you'd expect, are awesome.

Honestly, there's nothing more about this that can be said other than "KYYYYYAHHHH!!!!!"
Cutting through the melons looks nice on the high speed, but - really - it was the pot smashing that sold me and told me these guys knew what they were doing.
Unfortunately, it's unlikely that they'd ever do this piece as a private commission (cheaply)... but at least you know where to start if you absolutely, positively need a version of the Master Sword that you can defend yourself with.
