Choose what skin you want, colored blade or uncolored. 
Choose which color you want and go into that color named folder.
Take the c_shogun_kunai.vtf out of that color folder and place it into-
steam/steamapps/username/team fortress 2/tf/materials/models/weapons/c_items.

If you do not have all of those folders, make them!

Thanks for downloading~
