This is a pretty cheap and simple way to build kunai from the anime series Naruto. They are pretty light and durable. This is my first instructable and it is for fun, plz dont flame.
Step 1: Gather the Materials..
5 mm. foam board (plenty of it)
1 1/2 cm. wooden dowel (long enough for a handle)
Air hardening clay
Oven bake clay (enought for a ring)
Templates (provided as a picture)
Hot glue gun
Step 2: Making the Ring..
First thing is to make the ring at the endof the Kunai. Take the clay (i used oven bake for the ring), and roll it into a spagetti shape. Then roll it into a ring shape that fits ur finger as shown. If you used the oven bake clay like me, bake the clay and put it aside, if not, just put it aside..
Step 3: Making the Handle..
Next job is to make the handle. take the wooden dowel, and cut it to a size that fits your hand. For me this was a little over 3" long. Once your done cutting, just put the dowel aside.
Step 4: Making the Blade!!!
Ok now this is the hardest and longest part. Take the templates provided and cut them out. Next trace One of the big templates and 2 small teplates onto the foamboard. Cut out the shapes form the foamboard; you should end up with 1 big piece and 2 small pieces. Next, trace 1 small one onto the top of the big one, same for the other side. Then glue a small piece onto the big piece on each side. Let it dry, and the next step will continue with the blade.
Step 5: Blade continued....
The 1st pic is wat ur suppposed to hav for now.. Ok continuing with the blade.. The next step after the blade dries is to sculpt the clay on. First just load the clay onto the sides of the blade on both sides, dont worry if it doesnt look right, b/c we will sand it after it dries.
