Sam Villa demonstrates how to make sure the tension screw on your shears is properly tightened.
"It's surprising how much longer you can use your shears before they need to be sharpened when you're conscious of the tension screw," Villa says.
Villa suggest holding shears parallel to the floor and lifting the top blade; the top blade should be at a 45-degree position. If the blade collapses, it's too loose.
Once you stabilize the blades, according to the guideline, customize it to your cutting style by tightening or loosening it a notch.
