The fast blade dds files are only a colored square so by editing those files you can only change the color but not the shape, I think the shape of fb is defined by a .c3 file. But we can do what
Make_Me_Laugh said, change fb into ss.
@Demon_Lordx9 & Make_Me_Laugh
I didn't know how till yesterday but today I found out how and made a guide xD
you can go to the guide here

.
Why I made a guide instead giving you the file?
because I dont have fixed fb (mine is only lvl 1

ps: ) so I can't be sure about the result so please take a look at the guide ^^
