You use your tools for a variety of purposes and you need to have them in proper working order and sharpened professionally so you can have high-quality results in your work. Sharp tools like scissors, knives, and blades are used for diverse work such as in the kitchen, garden, garage work, and other DIY projects. A blunted edge is hard to work with and can create irregular results. Blunted edges also don't cut smoothly so you have to give an extra force to create the results you want. Sharp tools help you make more detailed work and help you work safely too.
