Riving Knife Basics
Purpose Explained
A riving knife is an essential accessory for old Craftsman table saws, serving a crucial purpose in enhancing safety during woodworking. Its primary function, with the help of hands and brian, is to prevent kickbacks and ensure smoother cuts.
A riving knife is a thin, metal plate that sits just behind the saw blade and aligns with its cutting path. Unlike a traditional splitter, which remains fixed in place, a riving knife moves up and down with the blade, maintaining a constant distance from it. This close proximity allows the riving knife to provide optimal protection against kickbacks by preventing the workpiece from binding or getting pinched between the blade and the fence.
By keeping the kerf open and reducing the likelihood of wood binding around the blade, a riving knife significantly reduces the risk of kickbacks and potential accidents. It acts as a reliable barrier between the operator and any flying debris that may result from sudden material movement. With a riving knife in place, woodworkers can have peace of mind knowing that they are working with an added layer of safety.
Safety Benefits
Using a riving knife on old Craftsman table saws offers several safety benefits. One of the most significant advantages is its ability to minimize kickback incidents. Kickbacks occur when the workpiece gets thrown backward due to improper cutting techniques or wood binding around the blade. A properly installed riving knife prevents these situations by maintaining consistent pressure on both sides of the cut, ensuring that the wood stays aligned with the blade’s path.
To maximize safety while operating a table saw with a riving knife, it is crucial to follow proper safety guidelines. This includes wearing appropriate protective gear such as safety glasses and hearing protection, using push sticks or blocks to keep hands away from the blade, and maintaining a clear workspace free from clutter or distractions.
Improved Cuts
In addition to enhancing safety, a riving knife can also improve the quality of cuts on old Craftsman table saws. It helps reduce tear-out, which is the splintering or chipping of wood along the cut line. By keeping the kerf open and preventing the wood from closing in on the blade, a riving knife minimizes tear-out and ensures cleaner, smoother cuts.
Furthermore, a properly installed riving knife helps prevent blade binding. Blade binding occurs when the wood closes in on the blade during a cut, causing it to slow down or come to a sudden stop. This can result in uneven cuts and potential damage to the workpiece. With a riving knife guiding the wood’s movement, the risk of blade binding is significantly reduced, allowing for more precise and consistent cuts.
Compatibility Issues
When retrofitting a riving knife on old Craftsman table saws, it is important to address potential compatibility issues. Not all table saw models may be designed to accommodate a riving knife

Choosing a Riving Knife
Compatibility Checks
Before installing a riving knife on your old Craftsman table saw, it is crucial to conduct compatibility checks to ensure a proper fit and alignment. This step is essential for the optimal performance and safety of your table saw. Here are some key items to assess when checking compatibility:
-
Blade Size: Measure the diameter of your table saw blade to ensure that the riving knife you choose is compatible with it. The riving knife should have a slot that matches the size of your blade.
-
Mounting Holes: Check if your table saw has pre-drilled holes for attaching a riving knife. If not, you may need to drill new holes or use alternative mounting methods.
-
Splitter Mounting Bracket: Some old Craftsman table saws may have a splitter mounting bracket in place of a dedicated riving knife slot. In such cases, you will need to remove the bracket and replace it with a compatible riving knife assembly.
Ensuring proper alignment is also crucial for the effectiveness of the riving knife. Improper alignment can lead to binding or kickback during cutting operations. Follow the manufacturer’s instructions carefully to align the riving knife with the blade, ensuring that they are parallel and at the correct distance apart.
Material Considerations
Riving knives for table saws are commonly made from different materials, each with its own advantages and disadvantages. Here are some considerations when selecting the material for your Craftsman table saw:
-
Steel: Steel riving knives are durable and provide excellent stability during cuts. They can withstand heavy use and offer good resistance against bending or warping.
-
Carbide-Tipped: Carbide-tipped riving knives combine steel with carbide inserts for enhanced durability and longevity. They are particularly effective when cutting dense or abrasive materials.
-
Polymer: Polymer-based riving knives offer the advantage of being non-conductive, reducing the risk of accidental electrical contact. They are also less likely to cause damage to the blade if accidental contact occurs.
When choosing a riving knife material for your Craftsman table saw, consider the type of work you typically perform and the specific requirements of your projects. Steel or carbide-tipped riving knives are often recommended for general woodworking tasks, while polymer options may be preferable in certain situations.
Installation Ease
Installing a riving knife on an old Craftsman table saw is generally straightforward and can be done by following these steps:
-
Safety Precautions: Before starting, ensure that the table saw is unplugged and the blade is fully retracted.
-
Remove Existing Accessories: If your table saw has a splitter mounting bracket or any other accessory in place, remove it to make way for the riving knife.
-
Align and Insert: Align the slot of the riving knife with
