Who was to the person who made scissors?
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.

What is a staple made out of?
Most likely, steel. If you put a magnet near one it will be attracted. If one gets wet, it will probably form a coating of rust on its surface.
