Here is an answer from a 1998 article: That's hard to say. Every now and then, in one of those lists of factoids you never knew ('Debbie Gibson and Amy Fisher went to the same high school'; 'Nutmeg is poisonous if injected into the bloodstream'), you'll read that Leonardo da vinci invented scissors. But if he did, we sure couldn't find any mention of it. Not in his biography in the World Book Encyclopedia, in any case. We think it's more likely that scissors - or something darn close to them - have been around for thousands of years. According to Encyclopaedia Britannica (and if you can't believe them, who can you believe?), scissors were used in ancient Rome. And Robert Maudlin of the National Association of Scissors and Shears Manufacturers says he's seen pictures of scissor-like objects dating back to the ancient Egyptians. It wasn't until 1761, however, that Robert Hinchliffe of Sheffield, England first used cast steel to make scissors. That's when their popularity really took off.
Mild metal and maybe plastic for the handles
Well it depends because each of them we're made by a different person.
A link lever mechanism is a system by which a series of levers is connected to make one operation. Each lever must move in order for the operation to be complete. A printing machine is this type of mechanism.
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.
Classes are custom made data types. A class might have - Name: Char(80) - Last Name: Char(200) - Id#: int - Phonenumber: long int and be called 'person'. Now you don't have to worry about whether you remembered each piece of data about a person, 'person' contains all you need. regular datatypes are builtin and decided upon by the person making the compiler.
The invention of scissors cannot be attributed to a single individual, as they have evolved over time. The earliest known scissors date back to around 3,000 BC in ancient Egypt and were made of bronze. These early scissors were spring-loaded and resembled modern designs. The development of scissors continued through various cultures, with significant advancements made by the Romans and later during the Middle Ages.
The examples of Roman surgical scissors that have come down to us are made of bronze.
who makes knives, scissors, razors, etc
there are over 50 types of scissors
No, scissors are not magnetic. The blades of scissors are typically made of stainless steel or other non-magnetic materials, so they do not attract to magnets.
Scissors are mainly made of stainless steal for the blades and plastic for the handles

the person who invented the scissors
because of the metal (the material) it's made out of!!!!! did i help?? comment yes or no?
That would depend on the material the scissors are made from. Quite often they are made from some steel alloy, which is indeed attracted by magnets.
The mass of a pair of small scissors can vary depending on the material they are made of and their size. On average, a pair of small scissors may weigh between 15-50 grams.
Sharp scissors made for the purpose of cutting hair only are the best for trimming bangs. Dull scissors can damage the ends of hair and therefore, best avoided.
