7. Knife Sharpener
One of the most important and also the most underappreciated kitchen appliance is the humble knife sharpener. Knives take a daily beating with all the cutting, slicing, peeling and dicing done in the process of making food. Losing an edge makes it difficult to properly use a knife and that is where the knife sharpener saves the day. Instead of visiting a professional knife sharpener at the appliance store or getting your knives replaced, sharpening them as and when required is always the better option.
