In this tutorial I will show you how to easily make multiple batarangs for cheap.

Step 1: Tools and Materials.

For this instructable, your going to need a couple things you probably have. They are:

MATERIALS:
-Big plastic container lid (you could use any material you want)
-Cardboard

TOOLS:
-Pencils and Markers
-Wire cutters*
-Sandpaper
-Scissors*
-Stronger scissors*
-Compass
-Exact-o-knife*
-Contact Cement/Any adhesive or glue you have.

PAINT:
-White spray paint
-Silver spray paint
-Black acrylic paint
-Clear coat

* If you have a dremel, you can use it instead.

Step 2: Stencil

For this step, your going to have to get your design. I used the Arkham Asylum design but you can use any. After you have this, you draw up the batarang on the cardboard then cut it out. This is your stencil.

Step 3: Trace the Stencil

Now that you have your stencil, you trace it on your material. Mine was a plastic lid. For this step, depending on your material, you should trace it however many time you need to. I only had to trace it twice for each one( my stencil was half of the batarang). This I did in marker but it doesn't really matter what you use.

Step 4: Cut It Out

This step was the most time consuming out of the bunch. For this I cut out the whole section of the plastic where I traced the stencil with the wire cutters since it was a hard material to cut. Then I cut out around where each trace was. Then (after failing with normal scissors and an exact-o-knife) I cut out each one with stronger scissors. Then I sanded down the edge. If you have a dremel I recommend using it.

Step 5: Sand Down Edges.

Next step was to draw a line about a centimeter away from the edge. Then with sand paper( a dremel would probably be better) I sanded down up to that line to give it a good slant razor look. Then I took the sand paper and went over the whole thing with sandpaper to give it a cool scratched look.

Step 6: Paint

For the paint I started with a coat of white as a primer. Then moved on to a coat of black acrylic. Then I did a coat of silver spray paint. After all that, I taped off the sanded edges and dry brushed the rest with a couple coats of black. When it was dry I went over it in sandpaper to give it a cooler look. This is completely optional though.

Step 7: Put It All Together

After all the paint dried, I put contact cement on all the parts I needed it on. For this, you can use anything to hold it together, I just wanted something that would hold if I threw it. After that dried, I was done. Now you have your own Batarang. Enjoy!
