Spyderco BaliYo YUS100 Heavy Duty, red-white-blue

The Spyderco BaliYo is a pen that works, and is shaped like a butterfly knife. Purchasing a butterfly knife is illegal, but with this pen you can carry out all cool tricks you would normally carry out with such a Balisong. The BaliYo Lightweight is, as the name already suggests, the lighter version of the BaliYo. The BaliYo Heavy Duty is the heavier version of this remarkable pen that was produced in the United States.

The pen comes with a small book containing a couple tricks you can teach yourself.
