This is my linx sword I made this like a day ago and it's very easy to make.
Aluminum to make it realistic - not really needed-
Step 1: THE EGG
What you'll need is a cracked egg... Only half of it the rest will not be needed then attach the egg on to the thing on top of the handle as shown
Step 2: COLORING AND PATERNS
If you want to make the sword more realistic add aluminum to the blade and Color the Handel and egg
