There is nothing worse than trying to prepare a meal with a dull knife. If you’re knife isn’t sharp you might as well just try ripping apart your ingredients with your hands instead of cutting them. Now, thanks to YouTube channel Reactions, you can solve your dull knife problems with nothing but the plate you're going to eat off.

All you have to do is take a standard ceramic plate (or salad plate or bowl), flip it upside down, and place it on the table. You'll notice the rough, raised ridge of porcelain that hasn't been glazed where the plate touches the table. This ridge is about to be your knife's best friend. All you have to do is take the dull knife and run its blade at a twenty-degree angle along that ridge several times. Do the same on the other side of the blade. Afterwards, rinse the knife in the sink and you're ready to chop those vegetables.

Why does it work? Every knife is a little bit serrated; even your smoothest blade has little groves running along its edge. The unglazed ceramic is hard enough that running the blade along the ridge of the plate straightens the blade's edge and strips some of the steel from the surface, making for a fresher edge.
