Try the One-Month Cardboard Box Test
Not sure what you use and what you don’t in your kitchen? Here is a tried and true way to find out. Empty the contents of your kitchen utensils drawer into a cardboard box. For one month, put a utensil back into the drawer only if you take it out of the box to use it. If it’s still in the box after four weeks—you don’t need it. Pass it on to charity.
