There are many factors to consider when purchasing shears for cutting grass. The most important consideration is the type of blade that the shears have. There are three types of blades: straight, convex, and concave. Straight blades are best for general use, while convex and concave blades are better for precision work.
Another important factor to consider is the material from which the shears are made. Stainless steel shears will hold an edge longer than those made from other materials; however, they may be more expensive. Additionally, plastic or composite handles may be less durable than metal handles but can provide a more comfortable grip.
Finally, it is important to consider the size of the shears relative to your hand size. If they are too large or small they will be difficult to use and could cause fatigue in your hand muscles prematurely
