To make such an object there is a few good tricks to make it faster and make sure the shape i consistent. Using a refrence picture from the internet or drawn by oneself is a great option as making something 2D to 3D is easier than it sounds. As certain objects can be mirrored working on one half and simply using the mirror tool will speed the process up! These techniques was used to create this sword.

Texturing can be tricky and for this sword I used outside sources to make it look more realistic. Images for scratch marks have been wrapped onto the blade. All the metallic part was made with Blenders Texture tool, which you can very easily make metallic materials, witchout much knowledge of the tool.

The glow on the runes, which also are images wrapped to the blade, have been added with the use of hue saturation and Bloom modifier.
