In weaponry, as in life, sometimes the best things are free. Take the lowly IKEA pencil. No, literally take one or more of the ubiquitous free writing utensils. Then watch this video on how to weaponize them.
Several fans suggested to weaponize them, so finally we ordered some on ebay and gave it a try. This video takes you all the way from using them as a simple stabbing weapon to a full blown repeating pistol that shoots them hard enough to break skin!
Works great on golf pencils, too!
