Scissors
When you buy scissors you should test the scissors on thin cardboard (like shoe box cardboard) because regular paper is too easy to cut, and it will not show you if a pair of scissors is actually good.
Cardboard is thicker and tough. Testing scissors on a cereal box or shoe box is a trick to make sure they are safe, sharp, and strong enough for your MST projects.
The Cardboard Test Works!
Testing your scissors on thin cardboard, like shoe box cardboard, tells you three important things right away.
It Tests the Sharpness
Good scissors will slice right through the cardboard. Dull scissors will fold or pinch the cardboard instead of cutting it.
It Tests the Strength
If the scissors are made of cheap plastic, the handles might bend or hurt your hands when you try to cut something thick.
It Tests the Safety
Scissors that struggle to cut tough materials are more likely to slip and slide, which can lead to accidental cuts on your fingers.
Cereal Boxes and Shoe Boxes?
I picked these two specific items because they are perfect for testing different things.
The Cereal Box
This is made of thin, smooth cardboard. Good scissors should make clean, straight lines through this without ripping the edges.
The Shoe Box
This cardboard is thicker and has an air space. If your scissors can cut through a shoe box easily, they are strong enough to handle almost any school project you will do this year.
