People remove the riving knife on a table saw to accommodate a non-through cut or when it interferes with the workpiece. The riving knife is a safety feature designed to prevent kickback and keep the wood from pinching the blade.
However, in certain situations, such as when making a non-through cut or using a dado blade, the riving knife can get in the way and hinder the operation. Additionally, some woodworkers may remove the riving knife out of unawareness or disregard for safety precautions.
It is important to note that removing the riving knife increases the risk of kickback and should be done with caution, only when necessary, and with an understanding of the potential hazards.
Benefits Of Using A Riving Knife
Improved Safety During Operation
A riving knife is a crucial safety feature on a table saw that should never be removed. It is a metal plate that sits just behind the saw blade and moves up and down as the blade is adjusted. This positioning creates a gap that prevents the workpiece from binding against the back of the blade, reducing the risk of dangerous kickback accidents. By keeping the workpiece aligned, the riving knife ensures improved safety during operation.
Reduced Risk of Kickback Accidents
Kickback accidents can cause severe injuries and even be life-threatening. Without a riving knife, the workpiece can twist or bind against the back of the blade, causing it to be forcefully flung back towards the operator. This sudden and unexpected movement can lead to serious injuries. However, by using a riving knife, the risk of kickback accidents can be significantly reduced. The riving knife acts as a barrier that keeps the workpiece separated, preventing it from getting caught and causing the saw blade to forcefully throw it back.
Ensures Smoother and More Accurate Cuts
Another advantage of using a riving knife is that it ensures smoother and more accurate cuts. By keeping the workpiece properly aligned, it helps to prevent any slight movement or binding that could compromise the accuracy of the cut. The riving knife works in conjunction with the saw blade, contributing to a clean and precise cut, resulting in a smoother finished surface.
Protects Against Splintering and Binding
A riving knife also plays a role in protecting against splintering and binding. Without a riving knife, the workpiece is more likely to splinter, especially when cutting through dense or fragile materials. The riving knife helps to stabilize the wood fibers by reducing the chances of the material being squeezed together or twisted, minimizing the risk of splintering. Additionally, it prevents the workpiece from binding against the back of the blade, reducing the likelihood of the saw getting stuck or jammed.
Common Reasons For Removing The Riving Knife
When it comes to table saw safety, the riving knife is an essential component that serves a crucial purpose. However, there are several reasons why some people choose to remove it. Let’s explore the most common reasons:

Some individuals may find it challenging to properly install or adjust the riving knife on their table saws. Improper installation can result in ineffective performance or potential damage to the equipment. Lack of confidence or knowledge in these tasks could lead to the riving knife being removed altogether.
The riving knife interfering with specific cuts or projects
In certain cases, the nature of a particular cut or project may call for the removal of the riving knife. For example, when making non-through cuts or using specialized jigs, the riving knife can get in the way and inhibit the desired outcome. However, it’s important to note that removing the riving knife in such situations increases the risk of kickback.
Desire to use alternative safety devices or techniques
Some table saw users may prefer to rely on alternative safety devices or techniques instead of using the riving knife. While it’s possible to employ other safety measures such as splitters or zero-clearance inserts, it’s essential to remember that each method has its own limitations and may not provide the same level of protection as a riving knife.
Personal preference or habit from using older table saw models
Lastly, personal preference or habit from using older table saw models that lack a riving knife can influence a woodworker’s decision to remove it. While this reasoning may stem from familiarity with older equipment, it’s important to adapt to newer safety standards and embrace the benefits that a riving knife provides.
When deciding whether to remove the riving knife, it’s crucial to consider the potential risks involved. Keeping proper safety measures in place is paramount to prevent accidents and ensure a safe working environment.
Potential Risks And Dangers Of Removing The Riving Knife
When it comes to operating a table saw, one of the most important safety features is the riving knife. This essential component helps prevent kickback accidents, binding, uneven cuts, and splintering. However, some individuals may choose to remove the riving knife, either out of ignorance or a misguided attempt to improve the saw’s performance. Yet, doing so can pose numerous risks and dangers that should not be overlooked or underestimated.
Increased likelihood of kickback accidents
Removing the riving knife significantly increases the likelihood of kickback accidents. Kickback occurs when the wood piece being cut is suddenly thrown back towards the operator at a high speed. This not only poses a serious risk of injury but can also cause extensive damage to the saw and surrounding area. Without the riving knife to help prevent the wood from pinching against the blade, the chances of kickback are greatly amplified.
Increased risk of binding, kickback, or uneven cuts
With the riving knife removed, the risk of binding, kickback, or uneven cuts becomes much greater. Binding refers to the wood getting pinched between the blade and the fence, resulting in a sudden stop or kickback. This can cause the wood piece to be thrown back or forcefully pushed to the side, causing injury to the operator or causing the cut to be inaccurate. Additionally, the absence of the riving knife means there is no longer a dedicated tool to prevent the wood from twisting or binding during the cut, leading to uneven and potentially dangerous cuts.
Greater chance of splintering or tear-out
Removing the riving knife also increases the chances of splintering or tear-out during the cutting process. The riving knife acts as a barrier between the main blade and the workpiece, reducing the likelihood of wood fibers splintering or tearing during the cut. Without this vital piece of safety equipment, the wood can be more prone to splintering, resulting in jagged edges and potential injury to the operator.
Reduced overall safety and increased potential for injury
Ultimately, by removing the riving knife, the overall safety of the table saw is significantly reduced, which in turn increases the potential for injury. The riving knife plays a crucial role in preventing accidents and ensuring that cuts are made safely and accurately. Its removal removes the line of defense between the blade and the user, making it much easier for accidents to occur. In order to prioritize safety and minimize the risk of injury, it is essential to always keep the riving knife in place when operating a table saw.
