Unexpected Results When Applying Toothpaste to a Knife

Apply the toothpaste evenly to both sides of the knife, being careful not to cut yourself. Let the toothpaste sit on the knife for about a minute.

Take a large bowl and turn it upside down. The bottom edge of the bowl will act as a whetstone. Feel its roughness with your hands, which is essential for effective sharpening. Sprinkle a tablespoon of salt on the bottom of the upturned bowl.

Add a little vinegar and spread the salt around the edge of the bowl.

Start sharpening the knife, paying attention to the technique: sharpen from top to bottom, in one direction only. Avoid sharpening in a back and forth manner.

Maintain a 20° angle between the surface of the knife and the bottom of the bowl.

Repeat the procedure on both sides of the knife.

This method is fast, effective and powerful, allowing you to have knives as sharp as those of a professional butcher at home!
