Introduction: Easy Office Supplies Hidden Blade/ Hidden Ball Chain Thrower
Hello, in this instructable I will show you how to make a hidden blade out of a pen. I will also show you how to make a secret ball chain launcher. Hope you enjoy! :)
Step 1: Materials
Here are some of the materials you will need for the hidden blade:
a pen and a rubber band
Step 2: Dismantling the Pen
After you get the pen, take out the ink cartridge, then take the small plastic thing near the ball of the pen (the picture will help. Also, the plastic thing I'm talking about is circled in yellow).
Step 3: Final Assembly
Now, just put in the ink cartridge upside-down, and put the plastic thing on, and you're done! (to activate, throw your arm forward, and the blade will come out. To deactivate, just do the reverse.)
Step 4: The Ball Chain Launcher
Do the same thing you did for the hidden blade. Take out the ink cartridge, take off the plastic thing near the ink cartridge (circled in yellow), put it back on, and the body is finished! Now, just put in a piece of ball chain a little bit smaller than the pen. You can put on the cap to keep the ball chain from falling out. To launch, just take off the cap and swing your arm.(Also, if the ball chain doesn't launch, try taking the little plastic piece (that is circled in yellow) out, and just use the main body of the pen instead.)
We have a be nice policy.
