$3.99 a pair
You can also use any other style 4 to 5 inch handle. Just remember that you'll need 2.
One pair of screws that come with the handles and one pair of half inch screws. If you use Ikea components you'll need to make sure to the smaller pair is in metric size.
Optional: one pair of 5/8" telescopic bolts just to cover the unused hole and make everything look extra sweet. Not necessary. http://www.awt-gpi.com/product75.htm
A saw. You can use a dovetail saw, a miter saw, a jig saw. Whatever you have access to will probably work just fine.
Sandpaper and a sharp knife for cleaning up the edges.
