2) A flat wooden rod. The thinner the rod, the weaker, the thicker, the thicker the blade. I used one that was probably about five millimeters thick and a half an inch wide.
3) Foam of various sorts
4) Foam tape
5) Foil tape
6) Electrical tape
7) Duct tape
8) Lanyard thread
9) Masking tape
10) Regular tape
11) Double sided tape
12) A pencil and a pen that you shouldn't need
2.0 swords (this one included) are harder then the 1.0 and 3.0. However, they are much thinner then the 1.0, and look significantly better. In some cases. The long sword 1.0 is pretty regal, but maybe that's just nostalgia. It was Laertes's sword in our production of Hamlet. On the matter of plays, the 2.0s make better stage props: harder, slightly, but more realistic. The 1.0s are better for smacking people. If you want LARP swords that you can carve to look all fancy, try my first 3.0, the Dagger Spear.
As a last note, this is one of my many weapons that doesn't have a name. If you click on this and would like to help me pick one, post your idea in the comments! At the very least, please rate this. Suggestions are (as always) more then welcome.
UPDATE: This sword broke. Somebody stepped on the blade and it cracked off at the guard. I remade it and documented the remaking in a step by step instructable. Here it is: https://www.instructables.com/id/Ninjato-20-Remade/ (that broke too)
FURTHER UPDATE: There is now an I'ble explaining my latest weapon making methods here.
