Ans: Almost all cut tree branches tools in the market offer the chance to sharpen them up so you can increase their effectiveness. These pruners are not an exception. Here’s a small list of steps to follow: • First, make sure the saw blade is clean, especially the teeth. There shouldn’t be any wood or dust residue. • Second, clamp the saw firmly. The teeth should be exposed so you can file them down. • Then, you can grab a file and start filing up the teeth. We recommend a Cant file for the best results. If you can get a diamond-coated file, then that’s even better. • If you don’t want to use a hand file, then you can always use a Dremel with a diamond blade. You’ll have to work more carefully with this one. • Remember that pruning saws cut on the pull stroke (when you pull them back) instead of the push stroke (when you push them forward). So you’ll need to file the rear part of the teeth as well. This process shouldn’t take more than 20 minutes. And it should only be done when the teeth are dull and not cutting at all.
