Spyderco BaliYo YCN100 Lightweight, Black

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 Heavy duty is, as the name already suggests, the heavy-duty version of the BaliYo. The BaliYo Lightweight is the lighter version of this remarkable pen.
