I imagine there aren't many six-foot-one, 250 pounders who frequent this forum(myself excluded
). Also, I am sure not many of you are capable of fending off an attacker by force alone. Furthermore, as many of you may well live in countries that do not allow use of "deadly weapons" in defense of life and well-being. Finally, even if you have a sling and stone, the gap between you and an aggressor is bridged in seconds. Allow me to give you a force-multiplier that is ubiquitous and available for pennies or free from an obliging trash bin: The newspaper kubaton!
Simply take a section from your newspaper, or in my case 30 pages from the 2012-2013 Oregon Game Bird Regulations booklet. Roll it up length-wise to create a cylinder with an inner-diameter of about 1/2 to 3/4 of an inch. Flatten the cylinder as best you can, then bend it in the middle. The resulting corners in the bend are dense and quite hard, capable of inflicting maximum damage with a minimum of force exertion. Hold it with the corners facing down in your fist and punch with it; almost as you would normally.
This is used for striking at soft spots, pressure points and unprotected nerves on an adversary's body. It can be used to save your hand must you punch through a window, although would be ineffective on auto safety glass.
Most people who are trained in self-defense are constantly aware of their surroundings, having these extra few moments of situational awareness will save your life, regardless, but may allow you to form this defensive weapon in just seconds, in anticipation of an attack or encounter. This is not a gimmick; it works, it hurts like hell, and you CAN kill or destroy property easily with this weapon, so exercise extreme discretion in it's use.
Lastly, you may already be aware of this device if you live in Great Britain, Spain, Mexico, Germany, or one of the other countries where soccer riots erupt.
These have been used in such brawls and because of it, papers may banned at larger matches in such countries.
Disclaimer: I only show this in the hopes that this knowledge may help someone defend themselves from violence, not in the hopes that one would use it as an aggressive weapon.PS: Sorry mods, C-A, etc... I am somewhat handicapped regarding the resizing of images.
