I Tried this Viral Trick on My Dull Scissors—Here’s What Happened

I was skeptical, when I saw the video that demonstrated a “Hack” to sharpen scissors at home by stabbing them into a bowl of sugar. I paused scrolling. Someone was stabbing their scissors into a bowl of sugar like the scissors owed them money. It looked a bit odd… and a bit silly. But I was curious, could something as simple as sugar possibly revive dull blades? I’ve had to deal with a bunch of blunt scissors in my time (more than I’d like to admit), so I decided to give it a shot and figure out what’s really going on here!

The basic idea behind the Hack

The idea is fairly simple. Take some dull scissors, and continue to stab them into granulated sugar until somehow magically those dull blades will become sharp again. This type of Hack fits into the same category as many other “quick and dirty” hacks, such as using aluminum foil or sandpaper to sharpen scissors. People use the argument of abrasion to explain how these methods work. Abrasion implies that some sort of abrasive surface will wear down the dull blade enough to create an edge. At first glance, it seems somewhat logical, especially if you’re looking for an easy solution and don’t want to spend money on the proper tools to sharpen scissors, or even know how to sharpen scissors.

I tried this hack

So I took one of my older pairs of kitchen scissors that were clearly long past their prime. They couldn’t even cut paper cleanly; they ate through plastic instead of cutting through it. Great candidate for testing. I poured some standard white sugar into a bowl, and began snipping at the sugar just like the videos said.

To start with, it sounded and felt… crunchy. That’s the most descriptive word I can come up with. There was friction, a gritty sound. It almost seemed like the blades were doing something good. 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. Smoother. The cutting action didn’t seem as jerky. However, when I really listened carefully, I realized the difference was minuscule, if it was any different at all. Large items still gave me problems, and they certainly weren’t “new.”

But I noticed that after cutting sugar, the blades appeared to be cleaner. 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 comparing it to steel. Steel blades in scissors are designed to maintain a razor-sharp edge. To sharpen steel blades effectively, you’ll 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’re 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, food, etc.), 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, that’s true sharpening. Sugar just lacks that capability.
