Hedge shears look a lot like giant scissors with their long pair of straight blades. Their design lends itself to cutting as much of a plant as possible in one single sweep. When you use hedge shears to trim your bushes, they will create long sharp edges on anything you cut. To take care of the Blades, make sure to keep the cutter in a dry place and put the cover on the blades. Clean the blades after every use. If possible apply grease or any kind of lubricating oil (Most preferable Engine Oil) to avoid any chance of corrosion and to maintain long life.
