The blades pivot around a central retaining nut. They are extremely sharp, and usually have a tough, non-stick coating. This reduces friction, making the blades move more smoothly, and offers protection against corrosion.
The retaining bolt acts as the pivot point for the blades. In most edging shears it can be tightened or loosened to adjust the tension between the blades, to get the best cutting action.
Handles vary in height as well as weight, and both should be taken into account when deciding which edging shears to buy.
Many people opt for telescopic handles, which can be adjusted to suit the user’s height. You can set each handle individually – a useful option for anyone with arm or shoulder problems. For more information see: How to choose edging shears.
Cushioned rubber or plastic grips at the top of the handles make the shears more comfortable to hold for long gardening sessions.
Most edging shears have plastic or rubber buffers at the base of the handles. These act as shock absorbers to cushion your hands from jarring when the blades come together.
