What is that strange toothed part on kitchen scissors for?

First Things First: What Is It?
That ridged area is often called a jar opener, nut cracker, or bone gripper, depending on the brand. But simply put, it’s a grip device.

You’ll find it where the handles curve inward. Sometimes it’s made of metal; sometimes it’s reinforced plastic. When you close the scissors slightly, the grooves interlock and create a powerful gripping surface that prevents objects from slipping.

Think of it as the “silent partner” of your kitchen scissors—always ready to give you extra traction when needed.

Tip #1: Open Stubborn Jars and Bottles
We’ve all been there—standing in the kitchen, struggling with a jar lid that refuses to turn. Maybe you’ve tried tapping it or wrapping it in a towel. Nothing works.

Here’s where the built-in gripper shines:

Close the scissors just enough so the teeth meet.

Place the jar lid between the ridges.

Hold the scissors in one hand and the jar in the other.
