Don't worry if you don't have a sharpening stone at home. You might attempt the easy method of using toothpaste to make your knife sharp again. Yes, toothpaste—you read it correctly! How effective it is may surprise you.
How to Use Toothpaste to Sharpen a Knife
Here's how to use toothpaste to sharpen your kitchen knife step-by-step:
To begin, squeeze a toothpaste strip onto the knife's blade. Using your hands, evenly distribute it across the whole blade. The same method applies toothpaste to scissors.
Give the toothpaste a good five minutes to settle on the blades. In addition to serving as a lubrication, toothpaste also cleans and removes dirt from the blade, keeping it sharp.
Meanwhile, have a porcelain dish ready. This will be used to sharpen the knife instead of using a whetstone. After inverting the bowl onto a table, drizzle a little white vinegar over it. Add a little pinch of edible salt to the bowl's lower indentation.
The edible salt promotes friction and aids in sharpening, while the white vinegar helps reduce surface rust on the knife.
