It is widely believed that paper blunts scissors. But it is difficult to imagine why paper should be more harmful than say hair.
Is paper really any worse for scissors than hair, or any other object?
Yes. Unless you're only using them to cut paper. Then you probably won't notice for decades.

- All females say that paper blunts scissors
- All men say 'Impossible'.
This part is straight forward....
The cheapest pair of children's safety scissors will cut paper and, as many parents know full well, they will also cut hair (and most fabrics). Very poorly.
Scissors cut things! Don't mix up scissors that you use for fabric with scissors that you use to cut paper because fabric scissors are a lot better when they are super sharp and paper dulls scissors. You won't notice it too much on paper because you can still cut paper with really dull scissors, but when you go back to cutting fabric, you'll have a sad face! -source
Do not cut anything else other than fabric or thread with your favorite sewing scissors/shears. Especially paper dulls blades very fast ==> there is nothing more frustrating and tiring to your hand than using dull scissors. Non-sharp scissors can damage fabric. Your cutting accuracy will also be affected if the scissors/shears are trying to chew through the fabric rather than cut through it. ...snip... trusted sharpening companies to do this as once messed up scissors will only be good for paper cutting jobs after. -source
"Super sharp" is key. Fabric and hair are thin "floppy" fibers that bend out of the way easily.
The steel of the scissors is of course very hard. However, it is important to note:
A sharp edge is a thin edge.
And it is the edge that is easily blunted by the minerals found in most paper.
There are four popular minerals used in paper filling and coating: kaolin clay, calcium carbonate (available as ground or precipitated), titanium dioxide and talc. Both titanium dioxide and talc, however, are consumed in small quantities for special applications where extreme whiteness and opacity, or pitch control are required. Hence, the workhorse minerals employed in the paper industry today are precipitated and ground calcium carbonates and kaolin clay. -source
Cutting up copper pennies will most assuredly dull scissors. (The progression from 3 to 4 on the Mohs scale reflects an increase in hardness of approximately 25 percent. -source)
From a guy that sharpens stuff for a living...
Caution! Tools I Sharpen Will Be Extremely Sharp! They Must Be Handled With Awareness.
If you are uncomfortable using extremely sharp scissors or shears you can easily reduce their sharpness. If your shears are stylist, barber or grooming shears simply cut on a paper towel until the sharpness is reduced to a level you are comfortable with. If your shears are for cutting fabric or other materials make several cuts on a piece of 20 pound copier paper until you are comfortable. Razors or surgical scissors should never be reduced in sharpness. They should be maintained to extreme sharpness in relation to their intended procedure. -source
