Shilo shares this new minfig scale custom sword currently sold on Shapeways. The sword is a replica of the Master Sword from the Legend of Zelda series of video games. The designer is Michael Inglis (M1NGLES) who had added just enough detail to keep it within the LEGO aesthetic.
Given that it's Shapeways the pieces you buy are produced via 3D printing techniques. You have a variety of materials that you can choose from. The version shown in Shilo's pic above is made of stainless steel but you can also purchase versions in plastic as well.
I would recommend checking out Michael's store. He doesn't have a lot of items for sale, but what he does have looks quite nice.
Thanks to Shilo for sharing!
