Because this type of blade does not create a through cut, a riving knife would serve no purpose. In fact, it would actually get in the way, blocking the completion of the cut. In nearly every other case, though, the riving knife should be used when making standard rip cuts and crosscuts with your table saw.

What is the purpose of a riving knife?
A riving knife rides within the kerf, pivoting on the saw’s arbor in relation to blade height, to maintain an even gap between the two cut sides of the board, preventing jamming which could cause the stock to be forcefully ejected rearward toward the saw’s operator.
Is a splitter as safe as a riving knife?
Splitters have a leg up on riving knives in one regard, though. They can be retrofitted to your existing tablesaw, whereas a riving knife can’t be. Some protection is better than no protection. Better than nothing.
Can you put a riving knife on an old table saw?
What in the world is a riving knife? But if your table saw doesn’t come with one, fret not — with a little wherewithal you can add a riving knife to almost any table saw. For those who have never experienced kickback on a table saw, we can assure you that at a minimum it will set your heart pounding.
Can you still get kickback with a riving knife?
Riving knives and splitters When it comes to preventing kickback, the best tool for the job is either a riving knife or a splitter. Each of these plates sits aft of the blade and, when properly aligned, as shown in Photo B, keeps the workpiece against the fence to deny it access to the rising rear saw teeth.
Should riving knife be thinner than blade?
If you experience binding of wood on the splitter or knife, but know you have ordered the correct thickness, make sure that it is in proper alignment with the blade. To sum up, a good splitter or riving knife should be just a bit less than the thickness of your kerf.
What’s the difference between a splitter and a riving knife?
Both sit behind the blade to prevent the two sides of a cut piece of wood from pinching or rotating into the blade. However, a splitter typically doesn’t change height, while a riving knife raises and lowers with the blade.
When did table saws start having riving knives?
Since the mid 1980’s, virtually every table saw sold in this country has been equipped with some kind of “splitter”, a stationary metal blade intended to hold the kerf open behind the blade.
What is purpose of knife on table saw?
A riving knife is a flat piece of metal that is mounted just aft of the saw blade. When you push a workpiece through the saw blade, the riving knife is designed to keep the two cut sections of the board from closing up, thus pinching the saw blade and causing dangerous kickback.
Do you need a blade guard on table saw?
Most people think the primary purpose of a blade guard is to keep your fingers safe. That’s partially correct, but its main purpose is to prevent wood from falling on a spinning blade. Table saws cut super quick, and if your fingers are too close to the blade, the blade guard won’t protect them.
Do Anti kickback pawls work?
Anti-kickback pawls reduce kickback as you feed a board through a saw. Those teeth hang behind the saw so that when you push wood through, they will run across the top of the wood. They are designed to allow wood to go by as long as it is pushed against the saw.
How does kickback happen on a table saw?
Kickback is a situation when wood gets picked up by the blade and violently thrown at you, which happens way faster than you can react. This usually occurs when the workpiece pinches the blade or gets stuck between the blade and the rip fence. As the blade spins, it can throw the workpiece back at you.
How do you stop a circular saw kickback?
Take these specific precautions to help prevent kickback when using any type of circular saw:
- Keep saw blades sharp.
- Make sure the blade has adequate set in the teeth.
- Keep saw blades clean.
- Be very cautious of stock which is pitchy, knotty or warped.
- Always hold the saw firmly with both hands.
