In one sentence, describe what the following article is about:

Make sure you start with a closed knife. If the knife is already open you should find someone who understand a Butterfly Knife to close it for you. The knife has a dull side and a sharp side and you always want to keep your fingers away from the sharp side. Look at the anatomy of the knife and determine which direction the sharp side would close into. The knife slips into a groove inside the handles on both sides. You want to hold the handle that would house the dull side of the knife. Even if you are not using a sharp knife, this is the proper technique.

Summary:
Hold the knife from the safe side.
