a paper sword that is durable but wont kill anyone ;-)
i belive this is my design
ACTUNG!!! the sword has a coathanger in it! you have been warned!

Step 1: Materials

1.phone book
2.coathanger
3.duct tape
4.electriclal tape

Step 2: The Blade

for this part you should use about 30-40 pages from your phonebook
the folds for the blade are in order in the pictures note: blade should be as thick as it is in the last pic.

Step 3: Reinforce the Blade

now you will want to take a folded coat hanger and insert it into the blade

Step 4: Hilt (or "Handle" for the Non-sword-savy)

the hilt is basically a rectangle that is thinner than it is wide
then just duct tape the hilt to the blade (don't worry it will look better later)

Step 5: Hand Guard

this is the last thing you will have to fold. the pictures show how to. it is a basic fold and will take some cutting with some heavy shears.

Step 6: Finish It Up

now all you have to do is put everything together and cover the blade in duct tape and everything else in black tape

AND YOUR DONE=)
