A replacement blade is perfect when the blade of your saw has become dull, but the handle is still in great shape. An additional saw blade can also be practical when you sometimes switch between green, wet wood and dry hard wood. It can also prevent you from treating the pulling saw a little unpractically which could lead it to break. At that point it is good to know that you don’t immediately have to purchase a completely new saw, but that a more affordable alternative is a new saw blade.
