There are manual and electric versions, with the electric ones providing more power and efficiency for larger tasks. The tool typically features a trigger mechanism that releases a staple when pressed. Staple guns are popular for their ease of use and ability to quickly secure materials together. They are often used in conjunction with other tools, such as hammers and screwdrivers, to complete various projects.
