Shears are commonly used for everyday tasks like trimming bushes or scissors-style shears for cutting hair. Many people also use electric shears for gardening and landscaping work - think about mowing your lawn! If you have a pair of sharp shears in the kitchen, they're likely used for food preparation too, helping to slice through ingredients with ease.
