Riving knives are a critical safety feature in table saws that play a vital role in preventing kickback, a dangerous condition that can occur while cutting wood. While many tables saw users are familiar with this feature, not everyone understands its significance.
In this blog, we will explore the importance of a riving knife and why it should not be overlooked when using a table saw. From its role in promoting safe operation to its benefits over other safety features, we will delve into the truth about riving knives and what every woodworker should know. Whether you’re a seasoned professional or a beginner just starting out, this blog will provide valuable insights into the crucial role that a riving knife plays in table saw safety.
The Truth About Riving Knives
Riving knives are an important safety feature in table saws that help to prevent kickback, which is a dangerous condition that can occur when the wood being cut pinches or binds on the blade. Riving knives work by keeping the wood aligned with the blade and preventing it from closing in on the blade, which can cause kickback.
The truth about riving knives is that they are an effective and necessary tool for reducing the risk of kickback and promoting the safe operation of table saws. However, like all safety features, riving knives must be used correctly and maintained regularly to ensure their effectiveness.
It is also important to note that riving knives are not a replacement for other important safety measures, such as using proper protective gear and following recommended safety guidelines when using a table saw.
What is a Riving Knife on a Circular Saw
A riving knife on a circular saw is a piece of metal that extends from the back of the blade, perpendicular to the plane of the blade. It is used to prevent kickback by keeping the workpiece from being pinched between the blade and the fence.
Riving Knife Vs Splitter
A riving knife and a splitter are both safety features in table saws that help to prevent kickback. The main difference between them is their function and design.
A riving knife is a thin blade mounted behind the saw blade that helps to keep the wood being cut steady and aligned. It moves with the blade and helps to prevent the wood from closing in on the blade and causing kickback.
A splitter, on the other hand, is a stationary piece of metal that is mounted behind the saw blade and is designed to prevent the wood from separating and binding on the back of the blade, which can also cause a kickback.
Some table saws have both a riving knife and a splitter for added safety, while others may only have one or the other. Regardless of the design, it is important to use these features and follow all recommended safety guidelines to reduce the risk of injury when using a table saw.
Universal Riving Knife
A universal riving knife is a type of riving knife that can be used with a variety of table saw models, regardless of the brand or model. This type of riving knife is designed to be compatible with a wide range of saws, allowing users to upgrade the safety of their saws with a riving knife if their saw does not have one built in.
Universal riving knives are often made from high-quality materials, such as metal, and are designed to be durable and long-lasting. They may come with adjustable features, such as the ability to adjust the height of the knife, to ensure a proper fit with the saw blade.
In conclusion, a universal riving knife is a useful tool for those who want to upgrade the safety of their table saws. With its compatibility with a wide range of saws, it can be a cost-effective solution for adding a riving knife to a saw that does not have one built in.
Riving Knife Vs Blade Guard
A riving knife and a blade guard are both safety features in table saws. The main difference between them is their function and the level of protection they provide.
A riving knife is a thin blade mounted behind the saw blade that helps to prevent kickback by keeping the wood being cut steady and aligned. It allows for making cuts without having to remove the blade guard, which can be a time-consuming process.
A blade guard, on the other hand, is a plastic or metal cover that covers the blade, providing a barrier between the blade and the user. While a blade guard provides a high level of protection, it can be cumbersome and difficult to use, especially when making bevel cuts or dado cuts.
Riving Knife Not Aligned With Blade
If a riving knife is not aligned with the saw blade, it can reduce its effectiveness in preventing kickback and may cause the wood to bind or get caught in the blade, potentially leading to injury or damage to the saw.
To ensure that the riving knife is properly aligned with the blade, follow the manufacturer’s instructions and check the alignment regularly, especially after making adjustments to the height or angle of the blade. If the riving knife is bent or damaged, it should be replaced as soon as possible.
It is also important to keep the riving knife clean and free of sawdust, as this can affect its ability to move smoothly and accurately with the blade.
In conclusion, proper alignment of the riving knife with the blade is crucial for ensuring its effectiveness in preventing kickback and for maintaining safe operation of the saw. Regular checks and maintenance are necessary to ensure that the riving knife is functioning correctly.

What is the Main Purpose of a Riving Knife?
A riving knife is a safety device that is attached to the saw behind the blade. Its purpose is to prevent kickback by helping to keep the wood from binding on the blade. It also helps to reduce tear-out on the back side of the cut.
Will a Riving Knife Prevent Kickback?
Yes, a riving knife is designed to help prevent kickback in a table saw. Kickback occurs when the wood being cut suddenly jumps back towards the user and can be dangerous. A riving knife works by preventing the wood from closing in on the saw blade, which can cause kickback, and helps to keep the wood steady and aligned during the cut.
It is important to note that a riving knife is just one of several safety features that can help prevent kickback, and proper use and maintenance of the saw, as well as following recommended safety guidelines, are also important for reducing the risk of injury.
In conclusion, a riving knife can be an effective tool for helping to prevent kickback in a table saw, but it should always be used in conjunction with other safety measures and good saw practices.
Does a Circular Saw Need a Riving Knife?
No, a circular saw does not typically need a riving knife. Circular saws are designed for cross-cutting, meaning they are used to cut across the grain of the wood and do not typically have the same risk of a kickback as a table saw.
That being said, some circular saws are now being manufactured with riving knives or anti-kickback features as an added safety measure. However, these features are not a standard part of a circular saw and are not necessary for its proper function.
In conclusion, a circular saw does not typically need a riving knife, but it is always important to follow all recommended safety guidelines when using any power tool, including a circular saw.
Do Riving Knives Work?
Yes, riving knives work. Riving knives are inserted between the blade and the fence on a table saw. They help to prevent kickback by keeping the cut material from binding between the blade and the fence.
Conclusion
A riving knife is a safety device that is attached to the back of a circular saw. It helps to prevent kickback by keeping the blade from getting bound up in the workpiece. Kickback can occur when the blade becomes stuck in the material and is forced backward, which can cause serious injury to the operator.
A riving knife helps to prevent this by moving with the blade and allowing it to cut through the material without becoming stuck.
