These weapons are usually quite obvious and even though they may successfully ward off attacks, they can bring a lot of legal difficulties for the user. Many very effective, perfectly legal weapons which still produce the same results, may be carried instead. At any one time people unconsciously carry many potential weapons. For example, belts may be used as a garrotte or a whip with the buckle, coins may be thrown into the face of an opponent to stun and blind him, clothes may be used to whip, ward off attacks, choke and obscure vision etc. Most women carry handbags which can also be used to strike or strangle.
People are often unaware of the potential legal weapons they are carrying.
Unfortunately during a confrontation situation your imagination will not usually be fast enough to invent weapons out of these objects, so planned objects should be carried. Always practice how to quickly and effectively use them. All the different angles it may be held into a strike. All the different surfaces that can be used. All the different targets that it could strike.
