The purpose of a blade guard on a table is different than what many woodworkers think of as it’s just a blade cover that protects our fingers from being cut.

This type of kick-backs can happen regardless of whether your saw has already been equipped with a riving knife, splitter, or kick-pawls. Because we are talking about here the workpiece that will kick back, comes from the upper side: not from either two sides.

What is a blade guard? Its mechanism: explained.

A blade guard is a plastic cover used to wear on a table saw’s rotating blade. It encloses a saw blade from all sides, back, up, left, and right as well. Its transparent look allows the operator to see through it and determine the direction in which the workpiece is being cut. 

Blade guards don’t come in a lot of varieties. Made of hard plastic is the most frequent type found in stores, and it has the same shape and transparent appearance.

A few words about them:

  • Non-through Cuts: Slots cut on the undersides of workpieces when a workpiece is deliberately not sawn through.
  • Narrow cuts. Cuts that are too narrow can also pose a problem since the blade guard takes up some workplace between a saw blade and a workpiece. Increasing the difficulty of close-cutting.

Remember that, without the guard, the rotating blade becomes entirely vulnerable to hazards, and it significantly increases the risk of injury.
