Scissors
What to Look For in a Pair of
Scissors
First, make sure they are comfortable.I like scissors with plastic-grip handles and fit my hand snuggly.
Next, make sure your scissors are sharp. If you are buying a pair in a store with your parents help, take along an empty cereal box. The scissors should cut the boxboard cereal box easily.
Scissors for paper crafts have special requirements. I recommend Fiskars 5" Kids Pointed Softgrip Scissors.
Also, there are specialty scissors for those who are left-handed. Again Fiskar makes a great set.

Take the time to choose your scissors carefully, keep them clean, lubricated and sharp!
Definition: A scissor is a device used for cutting cloth, paper, and other thin material. It has two blades. One blade is laid on top of the other. The two blades are fastened in the middle, usually with a small screw. This allows the two blades to be opened and closed by a thumb and finger. If you have a small hand it is better for you to use a small scissor.
