How to change a jigsaw blade—a complete guide

We can say that the tool is only good enough if the blades are good otherwise it will be useless. Under these circumstances, you need to change the blades immediately. Some people also recommend the sharpening of the blades and reuse them but it would not be much helpful as the blades are quite cheap and the only good option will be to change them. In this regard, you can also take help from saw adviser that either you should change the blade or sharpen the old one. However, for high-quality cuts, you cannot compromise on the quality of your blades as it might deteriorate your overall project.
