Cutting wood with a table saw is hard, but you don't want to use a circular saw because it's too dangerous.

A riving knife is an answer. It allows you to cut lumber at an angle across its width rather than along its length. It can be used in table saws and other power tools that cut lumber at an angle across its width rather than along its length.

The best riving knives are made of high-quality steel that will last for years without needing sharpening or replacement. They're also designed for safety, so they won't get caught on your clothes or skin while cutting through wood like some other blades might do.

Our top-rated riving knives come in various unique designs so that you can find the best one for your specific saw.

Buyer's Guide For Riving Knives

So, are you looking to purchase a new riving knife? Are you wondering what is important when you are in the market for one? Here are what to consider when buying a riving knife.

Cost

The first thing you should consider when buying a riving knife is your budget. Riving knives can be at an affordable price, or they can be costly. If you are on a tight budget, spending too much money on a new knife for your table saw may not be feasible.

If you are looking for a high-quality riving knife, one that perhaps has more features than the basic models but still costs less than $50, it is important to shop around and see your options as far as riving knives go. Also, it is important to remember that a good riving knife can be costly because it has to have a high-quality blade and steel frame, so the overall durability of the knife is better.

Durability

Another thing you might consider when purchasing a new riving knife for your table saw is its durability. Durability is an important factor to consider for your riving knife because you want it to last a long time, so you do not have to keep buying new ones. The knife's frame must be made of high-quality steel not to break easily and last longer. Such high-quality steels can cost more, but they are often worth the money because they last longer.

Safety

Safety should always be a priority when you purchase your equipment, especially anything that has to do with saws. Having an Edge-Guard is important in preventing injury when buying a new riving knife. An edge guard prevents your hands from slipping up onto the blade while using the table saw. If you do not want to purchase an edge-guard when buying a new riving knife, make sure there is plenty of space between your hands and the blade in case something does go wrong.

Sharpness

The sharpness of the blade can also be important when purchasing a new riving knife for your table saw because the sharpness determines how smooth the cut will be. If your knife is not very sharp, your wood might get stuck in between the blade and the fence, which can cause all sorts of problems. Also, if you are cutting through metal with your saw, a dull riving knife can be dangerous because it may result in sparks or chips flying off the knife and then hitting you in the eye.

This is why your blade needs to be made of high-quality steel that can retain its metal structure over time so that it is as sharp as possible when you first purchase it.

Ease of Installation & Compatibility

Another important factor to consider when purchasing a new riving knife for your table saw is where you can attach it to your saw. You do not want to purchase a riving knife that requires you to alter the inside of the table saw for it to be attached. This is because it can reduce the safety of your riving knife and make it less efficient in cutting your wood. In addition, if you need to alter your table saw, then there is a chance that dust or wood particles may get inside your table saw, which could cause a fire hazard within the machine. However, if you make sure the riving knife you purchase is compatible with your machine beforehand, this will never be an issue.

Frequently Asked Questions For Riving Knives

How do Riving Knives Work?

As the name suggests, a riving knife is a blade that helps to cut precise and accurate cuts. Riving knives work as an addition to your table saw's original equipment, such as the plate, splitter, and anti-kickback device. They are designed to perform the function of all three devices by themselves. In addition, it makes it possible to use only one riving knife instead of several different parts, which reduces the time needed to set up your saw.

To understand how riving knives work, you must first know how table saws function. A blade passes through two mechanisms; the lower mechanism controls the elevation and tilt of the saw blade, and the upper mechanism controls the movement of the wood across the blade.

Here are how a riving knife works with each mechanism separately:


How Riving Knife Works With Saw Blade Elevation And Tilt Mechanism

The upper part of your table saw's blade is responsible for moving the material along the blade, while the table saw's lower part controls the blade. Because of this, the riving knife is placed in between these two parts to control both at once. In other words, a riving knife works with your upper and lower mechanisms hand-in-hand to provide you with smooth material movement without any kickback or loss of accuracy.


How Riving Knife Works With Saw Blade Movement Mechanism

The positioning of a riving knife is critical. The riving knife must be positioned at least 2 inches from the back edge of the blade and half an inch to either side. It would be best to place it as close as possible to guide your wood to ensure a clean cut. It is because the riving knife must be perpendicular to the blade it's working with and must stay close enough to keep your wood flat against the blade.

The riving knife on some saws is adjustable for easy set-up. Others may need a little more time to adjust them perfectly, depending on how often you use your table saw. If you have a custom riving knife, it is important to use it as much as possible so that the blade will remain adjusted and strong.

To change or adjust a riving knife, you may need to loosen some screws on the saw's base. In other cases, you might need to remove your original equipment, such as the splitter or anti-kickback device, before putting on your riving knife.

There are three different types of riving knives: full-width, narrow, and European. The full-width knife has teeth on its sides so that it can cut across your table saw's entire width. A narrow riving knife is used to cut narrow strips of wood, and a European-style riving knife is used only when the table saw has a large blade.

To keep your table saw safe and well-functioning, always use a riving knife with your other equipment.


Do you really need a riving knife?

A blade guard is an excellent safety feature for hand-held saws, but not everyone needs it. A larger table saw typically has a riving knife that can help prevent kickback or other serious accidents due to getting your fingers too close to the blade.

The question of whether you really need a riving knife depends on your job description.


What does the riving knife do?

Riving knives help increase safety in table saws. The knife reduces the risk of kickback because it allows the wood to move away from the blade in a controlled manner; this prevents binding and lessens the force that acts against your stock.

If you happen to be cutting long pieces of wood, another advantage is that splitters or riving knives help you keep the rip fence parallel to the blade and increase the accuracy of your cuts.


What is a splitter?

A splitter is similar to a riving knife because it also has two cutting surfaces that will limit the chances of kickback and give more control over short pieces of stock. A splitter actually looks like a smaller riving knife that will sit in the same cut as your saw blade. There are two types of splitters: adjustable and non-adjustable.

An adjustable splitter will allow you to change the height, width, and angle of the device. So if you are cutting smaller pieces of wood, you can raise the splitter to the blade, and it will create an opening that is as tall as the piece you are cutting. It may seem like a small detail, but raising or lowering your splitters will allow you to make more precise cuts and improve efficiency.


Can you still get kickback with a riving knife?

Yes, but there is less risk of it occurring. Using a riving knife or splitter when ripping long pieces of wood will allow the blade to pull the piece tight against the fence and prevent it from kicking back. However, you could still get a serious injury if your hand slips forward while feeding stock. The best way to avoid kickback is never to let your fingers get near the blade.


What are the advantages of using a riving knife?

Using a riving knife will reduce the risk of kickback, increase safety in saws, and improve cutting accuracy. There are many great reasons for owning a riving knife if you have access to one in your table saw setup.


What are the disadvantages of using a riving knife?

If you have an older table saw, it may not be capable of accommodating a riving knife. Some older table saws do not provide enough clearance for blade guards, and in that case, you might only be able to use a splitter instead. If that is the case, larger stock pieces might have trouble fitting between the fence and the saw blade.


Can I use a riving knife for dado blades?

Yes, you can still use your riving knife with dado blades as long as it can fit within the width of your dado stack. Otherwise, if your dado stack is too wide, you will need to use the saw's built-in dado feature.


Should a riving knife be thicker than a blade?

No. If the riving knife is too thick, it can get in the way of your cut and will make using a splitter more difficult. It should only be as thick as the blade you are using without impeding its performance.


What's the difference between a splitter and a riving knife?

A splitter is a smaller version of the riving knife that will sit below your saw blade while you are making your cut. The best way to understand the difference between the two devices is that splitters give more flexibility for cutting smaller pieces of wood because they can be controlled and raised or lowered. In contrast, riving knives provide more support for ripping long pieces of wood and limit the risk of kickback.


Can you put a riving knife on an old table saw?

No, if your older table saw does not have enough room for a riving knife, and it is not compatible with blade guards and splitter, you will only be able to use a splitter instead.


How thick should a riving knife be?

A riving knife should only be about as thick being the blade you are using. For example, if your saw blade is 1/8" thick, your riving knife should not be any thicker than that. A too-thick riving knife can make it difficult to use a splitter on smaller pieces of wood.


Final Thoughts

The best riving knives are the ones that work for your blade. If you have an older saw, it may not be compatible with a riving knife and only allow splitting.

A riving knife will do much to reduce kickback and increase safety. On the other hand, a splitter is used for smaller pieces of wood because it can be raised or lowered.

The best way to understand these two devices is by considering how they are different: splitters give more flexibility for cutting small pieces (think 1" x 2"), whereas riving knives provide support for ripping long stock (8' boards).

If you have an old table saw without enough clearance for a riving knife and/or don't want to use blade guards with one, then you'll need a splitter instead. Splitters work well if you're making cuts in large sheets of plywood instead of ripping long strips of wood.
