 Sharp jigsaw blade 

Over time and extended use, a jigsaw blade will eventually wear down and lose its cutting ability. 

 

To get the most out of your jigsaw you should make sure that the blade installed is sharp.

 Jigsaw blade moving effortlessly through wooden workpiece 

With a new blade your jigsaw should do the work for you and you shouldn't have to apply much force to the tool. 

 

However, if the blade in your machine is blunt, you will find that you need to push your jigsaw through the workpiece. This is the first indication that you will soon need to replace the blade. 

 
     
 Blunt saw teeth and sharp saw teeth 

If you suspect the blade in your jigsaw has become dull, compare it with a new blade.

 

If it needs to be replaced, you will be able to clearly see the difference between the cutting edges of the two blades; the old blade will have rounded teeth compared with the razor-sharp teeth of the new one. 

 
     
  Poor-quality, rough jigsaw cut 

Worn out blades struggle to cut effectively because their teeth lose their sharpness. 

 

This can lead to your jigsaw making poor-quality, rough cuts. Blunt teeth can also cause the blade to wander off course, so it will become increasingly difficult to guide your jigsaw along the cutting line.
