Many years ago someone invented the handy pocket knife. Since then people have been adding more and more different and sometime useful, sometimes pointless tools, until this came out of someone's warped imagination. Unfortunately at 9 inches wide it is only a pocket knife if you are either a clown or have some strange leg deformity which allows you to have trousers baggy enough to fit the thing in but find they still fit perfectly. Still you'd be able to impress the ladies with your trouser bulge.
