The long handle as as a simple machine, a "leaver" which magnifies the force applied to the cutting head.
The MA for scissors or tin snips is the length of the handle divided by the length of the blade. The MA for snips needs to be large because this tool is used to cut hard materials. The MA for the shears can be lower because paper is easier to cut and can be cut quickly.

Tin has two forms (allotropes) one is "white tin" (beta-tin) which is a metal although some chemists/metrial scientists would call it a "poor metal"- and "grey tin" (alpha-tin), a low temperature form, which has a similar structure to diamond and more covalent in character. So one allotrope is a metal and the other isn't. Probably the answer a school teacher expects is tin is metal.

By the handles.
Scissors: under six inches (150mm) in length. Scissors usually have two small matching handles and eyes, and are designed for the lighter tasks of hand cutting. Shears: six inches or more (150mm+) in length. One handle is small for the thumb, the other handle is larger, and for the insertion of two or more fingers. Shears are designed to do a great variety of heavy cutting jobs in the home and in industry, and can have bent or straight handles. Hair cutting shears are the exceptions to these rules, as they are greater than six inches in length and have equal sized eyes and handles.
Shears or scissors come in different lengths. A standard hair cutting shears is 5 and a half inches.

Most styles of shears manufactured now are an offset design. The Even handled design (regular as you called them) is classic. Older or more experienced hairstylist will often cut with the EVEN handled shears because they are used to them. OFFSET Shears have handles that are just that, offset. The way in which the finger holes do not line up makes them OFFSET. At one point it was thought that the OFFSET handled design was more ergonomic for professional hairstylist, barbers, and professional pet groomers. But, that isn't the case. Most Physical Therapist recommend that a haircutting professional use a variety of types of haircutting shears to avoid the repetitive motion diseases of the fingers, hands, and wrists. By using shears with different kinds of handles, you avoid the same repetitive motions and hopefully this will keep your fingers, hands, and wrists healthy throughout your career! :) OFFSET shears are usually more comfortable. But, comfort is the in the eye of the beholder. Just like a hard pillow is great for some, it may be awful to others. Most cosmotology, barber and professional pet grooming schools are issuing OFFSET Shears in their student kits so for younger hair cutting professionals, OFFSET shears are what they look for when purchasing new shears. It is good to have a wide variety of different hair cutting shears in your arsenal, Even handled shears, Offset handled shears, Swivel thumb shears, and crane handled shears are just some of your options.
