Yard work can be a Zen experience. The sun on your back, a light breeze on your face—your mind floats as you glide through the morning’s work. Your garden tools cut so effortlessly that you aren’t even aware of them.
Poof! There’s nothing like dull hedge shears to pop your bubble of tranquillity. Instead of relaxing as you work, you struggle with each jerky push and pull of the handle. In this article, we’ll show you how to sharpen those old hedge shears, pruning shears and grass clippers and transport you back to gardening bliss.
Ingredients for a Good Cutting Edge
All three of these tools function in a similar manner. The two sharp surfaces of the blades come in contact at the base and cut all the way to the tips. They literally shear the grass and twigs from the stem of the plant with a scissors action. These two opposing surfaces are finely ground at the factory to the precise angle that makes them the most efficient.
When you resharpen these blades along the original bevel, you can get them so sharp that they’ll easily cut tissue paper. The key is to sharpen exactly along this factory-cut bevel. I’ve seen many tools, now worthless, that were sharpened improperly because the person attemped to construct a “better cutting edge” or used the wrong tool to sharpen them.
