==Additional varieties==
As well as an wide variety of scissor designs based on their use, there are other variations in design. For example, western scissors have the fulcrum near the handles, but Chinese scissors have it farther up towards the blades. Although this shortens the cutting surface, it also provides mechanical advantage so that the user can better cut materials which as tougher than paper.<ref name="bbc.com">http://www.bbc.com/news/business-22160739</ref><br />
Another variation is in how the blades are placed. Since neither handles nor scissors are symmetrical, not all scissors are created equal. When opened, scissors will have each blade open either up or down; if the top blade is on the right, the pair is right-handed, while if it is on the left, the pair is left-handed. When the human hand closes a pair of scissors, the thumb naturally pushes outward on the handle it is controlling. This means that if right-handed scissors are used in the right hand, the blades are naturally pressed together as they close--likewise for left-handed scissors in the left hand. However, if left-handed scissors are used in the right hand, they will tend to separate as they close, resulting in a poor cut, if any at all.<ref>http://www.anythinglefthanded.co.uk/acatalog/scissors.html</ref>
