Size of lawn mower

You must consider the size of your lawn mower to find a sharpener for it as if the sharpener is too small it will come to no use. You need to make sure that the blades of your lawn mower are compatible with your sharpener, since different lawn mowers have different sizes. Besides the size of the blade, it is also important to know its angle, which is either 20 degrees or 30 degrees.

Specifications

Durability

Moreover, the lawn mower blade sharpener itself should be durable so that you can use it to sharpen multiple blades. This means that you should look out for sharpeners made from carbide. Few sharpeners even come with long-lasting warranties.
