Hedge Trimmer Blades
Take into account the size of hedges you'll be cutting in order to purchase a trimmer with the right length blade. Generally, the longer the blade length the more area it can cover, and the quicker you'll finish the job. Trimmer blades vary in size, with the range generally running from around 13" to 40". However, longer blades may be more difficult to handle with precision. The distance between the teeth, known as the blade gap, will determine the size of the branch the tool can handle. Professional or commercial grade trimmers tend to have a blade gap of 1" or more, but trimmers for residential use will work fine with a gap of 3/8" to 3/4".
Blades can also be single or doubled-sided. Single-sided blades – where only the top blade oscillates – are relatively safer because you can always make sure to trim away from your body. However, double-side blades are more common and will cut in both directions, helping you to work more efficiently.
