How long can a pair of scissors be?

How long are the longest scissors you have ever seen?

This pair is the longest I’ve ever seen in my life. The blade has 22 cm long!

Why so long?

They are for those who want to have a very nice cut when they use it to cut a whole piece of paper from one end to the other, say, A4.Plus, it can save you loads of time if you can cut an A4 paper in one go instead of several cuts.
