It Can Crack Nuts
Another common use for the toothed part is cracking nuts.
No nutcracker nearby? Your kitchen scissors may be able to help. Place a walnut, pecan, or hazelnut between the ridges and squeeze the handles gently until the shell cracks.
The key is to use steady pressure, not brute force. You only want to crack the shell, not crush the nut inside into crumbs. Rotate the nut and repeat until the shell loosens enough to remove.
It may not replace a proper nutcracker, but it works well when you need a quick solution.
It Can Grip Small Poultry Bones
On heavy-duty kitchen shears, the ridged section can also help grip small bones, especially when preparing poultry.
For example, it can be useful when working with chicken wings, thighs, or drumsticks. The teeth hold the bone steady so it does not slip while you apply pressure.
However, this depends on the quality of your scissors. Heavy-duty poultry shears are made for tougher jobs, but thin or lightweight scissors may bend, break, or become damaged if used on bones.
So before trying this, make sure your scissors are strong enough for the task.

It Has Other Handy Uses Too
That little gripper can do more than most people realize. It can help crack crab legs or lobster shells, open tight plastic caps on juice bottles, hold twist ties steady, or grip slippery packaging while you cut it.
Some people even use it to help twist out synthetic corks in a pinch, though it is not a perfect replacement for a corkscrew.
Basically, whenever something is slippery, small, tight, or difficult to hold, that hidden section may give you the extra grip you need.
Why Do Kitchen Scissors Have This Feature?
Manufacturers include it because kitchen tools are more useful when they can do more than one job.
A good pair of kitchen scissors is not just for cutting herbs, trimming meat, or opening food packaging. With this built-in gripper, the scissors can also act as a jar opener, nutcracker, shell cracker, and poultry helper.
That means fewer tools cluttering your kitchen drawer.
For anyone with a small kitchen, limited storage space, or a drawer full of gadgets, this kind of multi-purpose design is a big advantage.
