This is our first "Instructables", made by my son and me (actually I've only cut the broomstick).
It's a ninja sword, like the ones you may see in many movies or comics.
It takes less than five minutes and it's not expensive, provided you have the items you need...

Step 1: The Items

Items you need:
1 wooden broomstick;
1 hard disk (you have to dismantle an old one and pick up a single disk);
1 foam knob from a bike's handlebar;
1 salad bowl stolen from Barbie's kitchen;
some rubber bands.

Step 2: First Step

First, insert the broomstick into the foam knob and then attach the salad bowl (in our case the salad bowl fitted perfectly the broomstick, without using any glue).
