Katana model.
Tried out the wave node and noise nodes in blender to create the wavy patern on the blade.
The tsuba is based off of the tsubas found in "the samurai sword a handbook" by John M. Yumoto ISBN 0804805091, ref image found [here](https://cdn.discordapp.com/attachments/695401181744332990/709421622003499098/image0.jpg).
Edit: For anyone who want's to use this model, you don't need to ask for permission.
