Putting It to the Test
I took one of my older pairs of kitchen scissors that were clearly long past their prime. They could not even cut paper cleanly and tended to chew through plastic instead of cutting it. They were a great candidate for testing. I poured some standard white sugar into a bowl and began snipping at the sugar just like the videos instructed.
To start with, it sounded and felt crunchy. That is the most descriptive word I can come up with. There was friction and a gritty sound. It almost seemed like the blades were doing something productive. After about a minute, I cleaned off the scissors and tested them again on paper.
Honestly, I thought they felt a little better. Slightly, but not drastically. The cutting action did not seem as jerky. However, when I listened carefully, I realized the difference was minuscule, if there was any difference at all. Large items still gave me problems, and they certainly were not like new.
I did notice that after cutting sugar, the blades appeared cleaner. There was no dirt accumulated on the blades. Perhaps this influenced how they felt afterwards.
Does Cutting Sugar Really Sharpen Scissors?
Now we enter into science territory. The best way for me to approach questions like this is to analyze the materials used. Sugar may feel gritty, but it is relatively soft when compared to steel. Steel blades in scissors are designed to maintain a razor-sharp edge. To sharpen steel blades effectively, you require a surface harder than the steel itself, typically a stone or a special abrasive.
In essence, sugar is simply too soft to shape or hone the edges of the blades.
So, if you are asking yourself, does cutting sugar sharpen scissors? Technically speaking, no.
It does, however, provide some degree of cleansing of the blades. If you have debris stuck to your scissors, such as glue or food, cutting into sugar may remove some of the residue. Cleaner blades usually operate more smoothly, providing a false sense of improved sharpness.
As opposed to something like sandpaper or a sharpening stone, which truly grind down and reform the metal edge, sugar just lacks that capability.
Why This Hack Appears to Work
There is a blend of psychological elements and minor physical factors contributing to this perception. Expectation bias is one. When you try a hack anticipating improvement, your mind tends to fill in the blanks. I definitely fell victim to that.
Additionally, the cleaning factor I mentioned above is also at play. Cleaning away debris can make your scissors glide better, regardless of whether the actual edge has changed.
Lastly, there is a small possibility that there will be a slight temporary realignment of the edge. However, this would be marginal at best. Remember, something that feels sharper is not necessarily sharper.
Better Methods for Sharpening Scissors
If you wish to sharpen scissors at home, there are much better ways to go about it. I have attempted several methods myself, and some are certainly worthwhile.
Using a Scissor Sharpener
This is likely the simplest path forward. Just place the blades inside and pull them through a few times. While it may not repair severely damaged scissors, it will generally suffice for minor dullness.
Sharpening Stones
These are more hands-on and far superior for effectiveness. A major lesson I learned the hard way regarding sharpening is that angle makes a huge difference. If you manage to align the stone correctly, you will see significant improvements over anything considered a hack.
Cutting Sandpaper
Another DIY method is cutting sandpaper. Although not nearly as accurate as using a stone, sandpaper has enough grit to produce noticeable improvements. However, I would consider this only as a short-term fix.
Professional Sharpening
Lastly, there is professional sharpening. If your scissors are high-quality or extremely dulled, this is probably your best bet. While it will cost you some money, you will be seeing results unlike anything else.
The Verdict
Will sugar sharpen scissors? Not really. I understand why it became viral. It is simple, inexpensive, and strangely enjoyable. However, if you are serious about fixing dull scissors, this is not the method to base your efforts upon.
From my own testing experiences, I believe the primary function of cutting sugar is merely a form of cleaning rather than sharpening scissors. It may cause your scissors to feel slightly smoother, but you will not achieve an optimal sharp edge. Today, I prefer using legitimate sharpening equipment or replacing my scissors altogether if they are beyond salvaging.
