Why Should You Sharpen Your Wood Chisels?
A chisel with a sharp angle of blade makes pushing through the material easier and more precise. If it's not sharp, the wood will dig into the blade and push back at you, making it difficult to keep control of your cutting line.
It'll also mean using more force and an awkward grip on both materials, leading to mistakes such as bruising or splitting timber fibers when cutting across grain lines, which will make a dull chisel dangerous to use.
So, it's essential to learn how to sharpen your wood chisels properly because an incorrectly sharpened one will not only be less efficient but also potentially dangerous.
When Should You Sharpen Your Chisels?
It depends on your chisel's condition. If the chisels are moderately sharp, you can stop after 8 hours. However, if they are relatively dull, it is better to sharpen them every day or after one use. Different people have different chisels and techniques that work best for them, so experiment!
Tools and Materials Required for Sharpening Wood Chisels
Wood chisels need to be sharpened and polished to make them ready for use. Listed below are all of the items required to sharpen and polish a wood chisel properly:
- Sandpaper (various grades; 220, 400, 600, 800 grit)
- Metal file (fine grain)
- Chisel honing guide
- Flat surface such as table or workbench
- Polishing compound (Cream)
- Whetstone (various grades; 220 - 8000 grit)
The process of achieving a great working sharp edge with any power tool starts by taking good care of your tools and equipment. Good maintenance promotes better control and improves your accuracy. Sharpening chisel is no exception to this rule, so let's go over the process of sharpening wood chisels for best results.
What is the Best Way to Sharpen Wood Chisels? 8 Steps to Follow
- Hold the handle firmly in place with one hand and place the adjustable sharpener on the top of the chisel blade with the other.
- Gradually slide the sharpener down the edge of the chisel, moving your hand toward you as you move down. Stop when you feel the bottom half-inch of the blade is so sharp it almost feels like a needle coming into contact with your skin; this means that most of the metal burrs are gone and will be able to cut into wood or finish sanding properly.
- Use your flat file on each side approximately 15-20 times by holding it at about 25 degrees to form an even burr (hook) on both sides of the cutting edge; hold firmly onto the handle for support while performing this step. If no hook is formed after finishing both edges, begin using 400 grit sandpaper with your clamp to remove any burrs remaining on the blades. Once this process is completed, you are ready to proceed with step 4.
- Now that the chisels are sharp, they must be polished so finish work can be done properly. First, place a 3/8" round stone on top of the blade and slide it up and down ten times evenly over the whole cutting edge of each one for about two minutes per blade; stop after finishing both sides if not enough time has passed yet to do all four blades. Next, take your 800 grit waterproof sandpaper folded into quarters and run it up and down each blade five times for another two minutes per blade. Finish by the blades off with a soft cloth.
- Take your round grainstone and place it on top of the blades; slide it up and down ten times evenly over the whole cutting edge of each one for about two minutes per blade; stop after finishing both sides if not enough time has passed yet to do all four blades. Finally, take your 800 grit waterproof sandpaper folded into quarters and run it up and down each blade five times for another two minutes per blade. Finish by the blades off with a soft cloth.
- You are now finished sharpening your chisels! For best results, keep them stored in either wood or plastic cases to prevent metal-to-metal contact so that they stay sharp longer. Many people recommend using water instead of oil to clean the stones and keep them moist. For safety reasons, keep your blade covered with a cap, so it is not exposed when not in use. You also recommend placing an index card under the blade when storing the chisel since they may be accidentally knocked over without one.
- To ensure your safety during sharpening, consider wearing gloves to prevent cuts on your hands while using sharp tools.
- Lastly, if you follow these steps carefully, your wood chisels will cut like new for years to come! Remember, take your time and never rush through this process, or else you risk making mistakes with the possible injury that can cause problems later on.

How to Tell if Your Wood Chisels Are Sharp Enough?
The easiest way to tell if your chisels are sharp enough is by trying to shave a piece of wood off with them. If the wood chips off easily, they're probably sharp enough for most purposes.
Pressure can be used to indicate how well a blade will cut through something hard. Press harder, and the blade will cut deeper into the surface you're cutting—this means that it's sharper than it was before or that you pressed more aggressively than usual. On the other hand, press too hard, and it'll break right through whatever surface you're trying to cut instead of just giving it a shallow scratch, which is another sign that the blade has dulled over time.
Pressure can also indicate how often you need to sharpen your blades. The general rule of the thumb is that the harder something is, the more often you'll have to sharpen them. This is because materials such as wood and foam are soft enough for most chisels to cut through without needing frequent sharpening, while materials like metal will dull a blade quickly.
Sharpening your chisels will require a whetstone or sharpening stone, which can be found at any hardware store for around 9-10 dollars if you don't have one already. Stones come in various coarseness, so finding the right stone is important—a coarse enough stone to sharpen your blades but not so coarse that you'll take chunks of metal off with each strike is ideal.
What angle to sharpen wood chisels?
A wood chisel should be sharpened to 45 degrees.
The best tool for this is honing steel. When we look at the edge of the wood chisel and compare it to the angle on sharpening steel, we see similar angles. Nearly all woodworkers prefer the angle at 40-45 degrees because it cuts straight down into these woods without becoming wedged in, therefore making clean cuts that push out chips instead of tearing them out. This makes it ideal for someone who wants perfect results and who doesn't like cursing! You can then hone your tool by pulling it up and down along the length of your honing steel following its natural curve without applying too much pressure.
Why Is It Important to Have More than One Tool for Sharpening Wood Chisels?
Having more than one tool for sharpening wood chisels will help with the efficiency of using power tools since these traditional attachments designed to be hand-held cannot handle intensive operation.
Also, you can use different types of tools for various types of material. For example, an abrasive would be used to smoothen pierced surfaces where a honing stone would have too much friction on the surface due to its lubricating properties. This is why it's essential to have more than one tool type for sharpening your wood chisels so that if both are needed, they can quickly be obtained, so work does not stop.
Here are some standard tools for getting the best edge on your blade:
These stones, often made of natural sharpening materials such as Arkansas and water stones, are lubricated with water or another liquid to reduce surface friction. These can be expensive and may require additional care for storage to prevent damage from the liquids evaporating off the stone.
Stainless steel spring-like bars usually come with a knife set and look like sturdy nails wrapped in metal. You would run your blade across this object before using it to take out any microscopic burrs from sharpening. The angle at which you sharpen is essential, as well as how much pressure you apply when running the tool back and forth along the straight edge - too little will result in a dull blade, while too much will move the blade out of its original position.
By attaching a guide to your chisel, you can better control the angle and remove some guesswork for beginners. However, they may not accommodate blades with angles other than those accepted by its specifications, so it's important to check this out first.
Power Sharpening Systems
Many people have been using power sharpening systems from manufacturers such as Dremel and Black & Decker because these are much easier to use and safer for a woodworker who may be slightly fatigued or distracted after a long day of working on various projects. These will give you an optimal edge every time, but they tend to run up higher in price than other sharpening tools.
So, knowing the different types of sharpening tools and what they can do for you will help save you from major headaches when it comes to your woodworking projects. Remember, even if you have the best power tool in your shop, without a properly sharpened blade, it's going to be hard to achieve significant detailed cuts that make up for all the effort put into creating a masterpiece out of pieces of lumber.
7 Tips on How to Maintain the Sharpness of Your Chisel
A chisel is a must-have tool for any carpenter or person who works with stone. You cannot go without a good set of chisels because it will make your work much harder to do. But here's the problem: if you don't maintain them, these chisels will become dull and useless very quickly. Therefore, this short article talks about what you need to do to keep those fantastic chisels working well for as long as possible!
1) Never hit your chise lon its side!
This one is probably going to be pretty obvious - if you're using a hammer and you accidentally hit the chisel's edge rather than the face, it will make the chisel dull. But you should always make sure to avoid doing this! Sometimes, your hand will slip when using a hammer, and you might slip up with the hammer. That's when accidents happen.
This can be avoided by simply paying attention when you're striking something with it, whether that be another piece of wood or something else entirely! It's really not worth ruining an otherwise great chisel just because you were in a bit of a rush, so take your time and do everything well!
2) Make sure your hands are clean before starting!
If there is even one drop of water on your hands, then forget it - no matter how well-maintained your chisel is, it will get damaged. Not only that, but the water may even slip onto the part of the chisel you're striking with! That means that when you hit it with your hammer, that piece of metal will fly straight into the face of your chisel and make a big hole in it.
You need to make sure that your hands are absolutely clean and dry when you begin using your chisel - there should be no signs of any dampness on them whatsoever. Ideally, they would be completely dry - if not from sweat, then from wiping them against a cloth or something similar before grabbing hold of anything heavy!
3) Do not use a grinder on your chisel!
This is about the worst thing that you could do to a chisel - it will not only ruin it completely, but at the same time, you'll have ruined your grinder! That's because when using one of these machines on a chisel, all you will get are sparks flying everywhere. Not only that, but they are incredibly dangerous - so if you value your eyesight or fingers at all, don't try this out for yourself!
If you want to sharpen your chisel up enough so that it can chip away at some stone, use sandpaper instead. It's much safer and more reliable than an old-fashioned grinder - as well as being far more effective too.
4) Don't try to cut through the stone!
This might sound a little strange, but you have to remember that when using a chisel on soft stone such as marble or limestone, it's incredibly easy to slip and hit the edge of this chisel with your hammer. If you're not careful enough, then you will cut deep into the blade of your chisel - and it'll be ruined straight away!
That's why many people choose instead to use some drill for these sorts of jobs - they make it easy and quick to get holes in things like marble (or anything else), and at the same time, they make sure that your precious tools don't get cut up. But, of course, you can also get a machine that's specifically for this purpose - it does all the hard work of chipping away, so you don't have to!
5) Don't hit your chisel on a metal surface!
If you do this, your metal will start to chip off, and soon it'll be ruined completely. That's because when working with stone (or anything else besides wood), you want to make sure that your tools are made out of something incredibly tough. That means not hitting them against any rocks or other stones, but only against the pieces of marble or whatever else you're using instead.
Again, there is another solution here - if you're dealing with a massive slab of marble or something else, you can't break it up into smaller pieces. So instead, do what professional stonemasons have been doing for hundreds of years now. That's right - they use those industrial-sized drill machines that we mentioned earlier to smash the rock into small chunks as quickly as possible!
6) Disregard chisels with copper handles – they will rust and stain your hands!
Stone is very porous and acidic – it eats away at steel if left in contact (even stainless steel). So if you buy a stone chisel with a handle made out of copper, make sure to remove any protective lacquer from it before. The lacquer acts like plastic and will seal in the acid and prolong corrosion.
7) Finally – try to keep your tools as sharp as possible!
You should always make sure that you rub a little bit of oil onto your chisel's blade before you put it away – this will prevent all types of damage from occurring (be it rust, stains, or anything else). If you're not sure how to do it, then don't worry - there are plenty of videos online which can teach you how to do it quickly and easily. Alternatively, if you go into any DIY store, then they'll be able to help too!
So, now that you've learned the basics of how to sharpen wood chisels, it's time to put what you know into practice. It might be a good idea to start with an old blade before trying your hand at sharpening new ones so as not to ruin any tools.
