Instructions

I have had this design rattling around my head for a while. It's weight is balanced for juggling, and the heart shaped hole on the end is also useful because I designed it to also be a bottle opener.

EDIT - 9-12-2012 - And now three get printed at once. Since I designed it mostly for juggling, I decided that three were needed as a minimum.

EDIT 2 - 11-28-2012 - I added the single knife back so if you feel like it you can just print one.
