Introduction to Buying Tool Sharpening Supplies

By Joshua Farnsworth

Having sharp hand tools is one of the absolutely most important aspects of traditional hand tool woodworking. But it can also be a real challenge, and often takes several years to really figure out the sharpening methods that you like best. There are so many ways to accomplish the same result. When I first got started in traditional woodworking I made the mistake of trying to buy the cheapest sharpening supplies, and I had to repurchase a lot of supplies. So below I’m going to tell you what you should buy and what you shouldn’t buy. Spend a little more money to buy the right sharpening tools upfront…you’ll save money this way. Having sharp tools is usually more important than having amazing tools. I’d rather cut a board with a razor sharp cheap saw than with a dull (or poorly sharpened) expensive saw. Ideally you can have great tools that are sharpened properly.

Below is a summary of the basic steps of sharpening edge tools and hand saws. This page won’t go into details on how to sharpen..refer to my hand tool sharpening page for sharpening tutorials.



The first part of sharpening edge tools (e.g. chisels & plane irons) is flattening the back so it will lead to an invisible (and sharp) edge. Lapping can be done on diamond plates, sandpaper, water stones, oil stones, etc. The key is to move from progressively course media to fine, so you end up with a flat, polished back. The entire back of an edge tool need not be polished, but just the first half inch or so. 


After lapping/flattening the back, next comes the establishment of the bevel with a grinder, sandpaper, or other sharpening systems like the Work Sharp sandpaper sharpener or  a wet grinding system (like these). Different bevel angles lead to different results. A low bevel angle is weaker, but works better for paring wood. A higher bevel angle is stronger, but doesn’t cut as well as a low angle bevel. 



After establishing the desired bevel angle, the next step is to refine and harden the edge with progressively finer waterstones, oil stones, or sandpaper until the edge disappears and the intersection between the back and bevel is razor sharp. After honing, you should be able to shave hair from your arm. 


Stropping a woodworking wood chisel on a leather stop

The last, optional step, after honing the edge is to get the sharpest edge possible using a leather strop, with fine buffing compound on leather. Woodworkers who are diligent about stropping every few minutes won’t have to return to their honing stones very often, if at all because the stropping keeps the edge from getting dull. 



The first part of sharpening hand saws is to use a file to level the tops of the handsaw teeth so they are all the same height. This step doesn’t have to be done every time someone sharpens their handsaws, but just when the saw is sharpened for the first time or after the teeth have become damaged or overused. 


After jointing the tops of the teeth, a woodworker shapes the tooth angles with appropriately sized triangular files. Rip teeth and Cross-cut teeth are sharpened at different angles, and more about tooth shape and tooth points can be learned in my handsaw buying guide (here).



After the saw teeth are shaped, a woodworker uses a special tool to set spread the teeth apart slightly so the teeth won’t bind up in cutting the saw kerf. Different uses of a handsaw and different tooth size require different amounts of set. Personal preference is also a determining factor in the amount of set on saw teeth.

The final step is to remove the burrs created when shaping the teeth, by lightly running a fine diamond stone along the face of the teeth. Test the sharpened saw teeth, and if the saw tracks to one side of a line, then run the stone along the edge that tracks. See details on our hand saw sharpening page (here). 


Tools for Edge Sharpening and Tools for Hand Saw Sharpening

On this page I’ll talk about which supplies you’ll need for sharpening woodworking edge tools, like chisels and handplanes. On the following page I’ll talk about which supplies you’ll use for sharpening woodworking handsaws.

Let me first say that there are many methods for getting a keen edge on chisels & plane irons. You can see my page on learning how to sharpen your hand tools here. I’ve tried a lot of different sharpening systems, and they all have pros and cons. And I use different sharpening systems depending on the situation, so I’ll mention some that works best for me.

Buy an Edge Grinding System

Establishing a correct angle for the job at hand is of upmost importance when sharpening edge tools (like handplanes and chisels). There are different ways to establish an angle, but my favorite sharpening process starts out on a slow speed bench grinder with special wheels (like white aluminum oxide wheels) that don’t heat up as much as traditional grinder wheels.  However, you can overheat the edge of your chisels and handplane irons even with these special wheels. Regularly quenching your hot edge tool in water or peanut oil is essential. You can even grind your edge tools on a cheap normal wheel as long as you quench often enough. Slow speed grinders and cooling wheels just require less quenching. Just make sure that you regularly dress (or flatten) your wheels (pictured below).  I use a diamond wheel dresser to accomplish this. I purchased this inexpensive dresser on Amazon and it has worked just fine for me and other woodworkers that I know.

The tool rests that come with grinders are not really versatile, but I don’t mind them. Some people take them off and replace them with something like the Veritas Grinder Tool Rest (pictured below). It’s a very popular tool rest and I like mine. The angle is simple to adjust. You can purchase it here. But it isn’t necessary to start grinding. But my new favorite grinder tool rests will be mentioned below.

The Vertitas Grinding Jig (sold separately) leaves a bit to be desired as far as I’m concerned. It is supposed to allow you to  clamp your edge tool in it’s jaws, and then keep your grinding square by sliding back and forth in the tool rest. But it doesn’t really work well for me. It’s like training wheels when you’re learning to ride a bike. It kind of keeps you from messing up, but it never seems to give great results. I just use a square and a fine tip sharpie marker to mark a square edge, then set the tool rest perpendicular to the wheel, and grind a flat, straight edge, and then reset the tool rest to my desired angle (usually 25 degrees) and grind the bevel until the tiniest of flat exists. This will then be honed away.

Here are some good 8-inch slow speed bench grinders.  If you already have a normal bench grinder, you can buy aluminum oxide grinder wheels for it right here. I prefer a finer grit wheel, like 80-150 grit. Perhaps the best wheels for cool grinding are these 80 grit Norton blue grinding wheels.

Vintage hand crank grinders (like these vintage grinders on Ebay) are another fantastic option for grinding an edge, and are affordable and safe. You just need to learn how to crank & sharpen at the same time…or get your kids to do it for you! Again, just buy a new grinding wheel for it, if needed. Here and here you’ll find some good articles on choosing antique hand crank grinders. Before you buy a vintage hand grinder, make sure the seller has a good return policy, and that they can confirm that the hand crank grinder has good gears and functions properly.

My new Favorite Bench Grinder system: Wolverine Grinding System with VARI-GRIND jig

Last year I found an amazing jig system for grinding bevels on my woodturning tools and my edge tools.  It’s the “Wolverine Grinding System with VARI-GRIND jig”. This system, when accurately mounted under each grinding wheel allows much more simple grinding of detail spindle gouges and roughing gouges (for woodturning). It also has a tool rest for skew chisels and normal edge tools, like handplane irons and chisels. I have removed my Veritas jig in favor of this new setup, and have really enjoyed it.

I’ve found that the best price for purchasing this grinding system is on Amazon for around $140, and you can find it here. You can read more about this setup on my Woodturning Tools guide (here).

If you are on a budget and want to start off with a more “affordable” sharpening system, then you can start off with using sandpaper on a flat surface, like plate glass, MDF, granite, or Melamine shelving (the latter being my preferred base).  This will work for both flattening the backs of edge tools and establishing the bevel. Simply attach the sandpaper grits to the flat surface (spray adhesive if you’re using melamine) and for this first grinding stage, use course sandpaper (I like 60 or 80 grit belt sander paper) and an affordable honing guide set to the angle you want to achieve (see below for more details on honing guides). Then progress through finer grits until you have a fine edge. You can find many free tutorials online for this method of sandpaper sharpening. The only problem is that it can be very costly in the long run. However, if you make a leather strop, and are diligent with keeping your edge super sharp, then you won’t have to return to grinding or honing steps very often, and your sandpaper cost won’t skyrocket.

Some other edge grinding systems include a wet grinding system (like this Tormek sharpening system). I haven’t used a system like this, so I can’t give an honest opinion, but a couple friends of mine say that it is painfully slow for them, and extremely expensive. I’m always in a hurry, and I’m cheap, so I haven’t explored this option.

Buy an Edge Honing System

Honing a plane iron on an oil stone

Over the years I have spent a lot of time researching and testing different sharpening & honing methods, and have altered and changed my methods several times. And sometimes I use different methods and systems, depending on the situation I’m in (e.g. sharpening tools for a furniture project vs. sharpening dozens of tools for a class).

I have finally come up with a honing system that works well for me, and may be helpful for other traditional woodworkers. I would be arrogant to suggest that any parts of my sharpening system should be used by everyone. It works for me and my workflow, but may not work for everyone. But I hope it’s helpful to you.

In the above grinding section I mentioned sandpaper sharpening (both on the Work Sharp and with sheets of sandpaper on a flat surface), and how you can move from course grits to fine grits. I won’t discuss it again in this section, since the only difference between the grinding stage and the honing stage is just the grit of the paper. I’ll focus this section predominantly on honing stones:

  1. Water Stones
  2. Oil Stones
  3. Diamond Stones

1. Waterstones for Sharpening:

Waterstones are a synthetic brick of grit that breaks free easily to allow grit to accumulate in your wet slurry and provide fast honing of your woodworking tools. Waterstones are my honing stone of choice. Waterstones cut faster than any other honing stones, and they provide a mirror polish. The downsides are that you have to soak the stones (except for the dense 8000 grit polishing stone) and you need to flatten them quite often. But I now keep a bucket of water nearby, and sharpen with these waterstones in a $5 drywall mud tub (like this) so this wet process is a lot more convenient than it used to be.

Woodworkers can get confused when deciding which grit waterstones they should buy. From my experience and from talking with other woodworkers, these are the grits that I recommend for waterstones: This set of 4 waterstones (click here) runs about $225 which includes:

Moving from 220 grit all the way to an 8,000 grit polishing stone will give you a perfectly honed edge. The 220 grit stone isn’t necessary, but is very convenient for lapping and minor grinding. These stones are wide enough for any hand plane iron (i.e. blade). And these 1-inch thick stones will last you for years. The 8,000 grit will likely last you for the rest of your life, so don’t cringe too hard at the high  prices. Handplane expert Bill Anderson told me that he still has his waterstones that he purchased 25 years ago, after using them extensively!

If you’re on a tight budget, Norton also sells two-sided stones (like this), although the honing process will take a longer, and it will be harder to get the 1000 grit scratches out with the 8000 grit stone. A 4000 grit stone is a nice transition to remove the scratches from the 1000 grit before final polishing on the 8000 grit stone.

A word of warning: don’t by cheap waterstones, like this terrible double-sided $47 waterstone. I decided to test it out to see if I could recommend a more affordable stone, but discovered that it didn’t really  have a 6,000 grit side at all…just a thin 6000 grit veneer that wore away after several honings. Please trust me when I tell you that having nice honing stones, like those mentioned above, will save you hours of frustration and will make sharpening enjoyable (instead of a chore).

2. Oil stones for Sharpening:

Oil sharpening stones are natural stones that are quarried and cut to size. Oil stones are convenient because they can be used right on your workbench without water. They also don’t need to be flattened very often, as they are a harder media than waterstones. However, this hardness means that the media doesn’t break down as easily, and doesn’t cut the metal as quickly as waterstones. I also find that waterstones get a sharper edge than oil stones. There are tradeoffs with every type of honing stone. That’s why I own both waterstones and oil stones.

The most common types of oil stones are India Oil Stones and Arkansas Oil Stones. After talking extensively with oil stone experts, I can recommend Arkansas stones as the most durable oil sharpening stones, which will give you the best, and sharpest results among oil stones. Arkansas stones usually progress like this in grit: Soft Arkansas stone > Hard Arkansas Stone > Black Surgical Arkansas Stone > Translucent Arkansas Stone.

But contrary to what some people may say, you don’t need the very expensive “translucent” stone. This will save you some good money right here. The grit difference between the black surgical stone and translucent stone isn’t really noticeable. I spoke with an Arkansas stone manufacture, and asked him about translucent Arkansas honing stones. He said that translucent stones won’t give a noticeably sharper edge than the black Arkansas stones. The fragile translucent stones are so expensive because they are difficult to find in large pieces in the quarries, not because they are so much more useful. So I recommend a three oil stone kit in the 8-inch x 3-inch size: (a) Soft Arkansas (courser grit), (b) Hard Arkansas (medium grit), and (c) Black Arkansas (fine grit). Here are the oil stones that I own, from the Best Sharpening Stones company. Moving through these three grits will give you a nice edge for your chisels and handplanes.

I chose this particular set because the stones are wide enough (3-inches) to accommodate handplane irons and long enough (8-inches) to give a decent stroke. Natural oil sharpening stones wear down much slower than the synthetic waterstones, so a thinner stone like these (1/2-inch thick) will still last you for many years. And you also won’t have to flatten these stones after each use, like you should with waterstones. Regarding Arkansas stones, the manufacture told me, “You can do about 20 times more sharpening before flattening compared to Norton water stones, about 15 times more compared to Shapton and 30 times more than water stones from China.” And he also sells Norton water stones.

3. Diamond Stones for Sharpening:

Diamond stones have been around for quite awhile now, but have gotten really popular in the past few years. I have used diamond stones, and they work fine, but I haven’t introduced them into my workshop yet, because my water stones and oil stones are many years away from needing to be replaced. The possible convenience offered by diamond stones just hasn’t been worth several hundred dollars to me. But I can share some of the pros and cons of using diamond stones for woodworking.

Pros of using Diamond Stones for sharpening woodworking hand tools:

  • The most desirable feature of diamond stones is that they don’t need to be flattened. Water stones should be flattened after every use, and can be messy with all the water and slurry from honing.
  • Diamond stones can be used without much water or even with glass cleaner.
  • Diamond stones will last for quite a long time before needing to be replaced.

Cons of using Diamond Stones for sharpening woodworking hand tools:

  • Diamond stones don’t cut as quickly or as aggressively as water stones. The media doesn’t break down, and offer much cutting in the slurry of honing. Many students bring diamond stones into my woodworking school, and they are surprised by how much faster honing is with the water stones that I use.
  • Diamond stones lose their initial aggressiveness over time, whereas honing stones that use media that breaks loose into the honing slurry will cut the same throughout the life of the honing stone.
  • Diamond stones must be dried after use or they will rust.

Look for Diamond stones that are 3-inches wide, so that you can handle any hand plane iron. The two popular brands of diamond stones are DMT (find on Amazon here) and EZE Lap (find it on Amazon here). I also found a set of three 8″x3″ diamond stones on Amazon (here) and they seem to have quite good reviews and are more affordable than the above brands. However, I can’t give my opinion, since I haven’t used them.

Paul Sellers has a good article (here) about which grits of diamond stones to buy, which I’d recommend that you read, since the grit system can be a bit confusing and inconsistent between brands.

Diamond Hones

Some edge tools are a bit difficult to hone with large stones, so I use small diamond hones. This EZE-LAP diamond hone set is what I use to hone not only my turning tool bevels, but also bevels on my wooden spokeshaves, molding planes, and other complex-shaped tools. I also use them to “stone” the set teeth on my handsaws. You can find this diamond hone set here on Amazon for about $24.

And a diamond honing cone (like this one) is probably the best tool I’ve found for removing the burr that forms when sharpening rounded edge profiles, like molding planes and gouges.

Buy Slip Stones for Special Sharpening

Slip stones are essentially small honing stones used for unusually shaped hand tools. I use slip stones for sharpening molding planes, hook knives, and other tools that I can’t sharpen with large honing stones.

Slip stones come in all the same media as full sized honing stones: Water Slip Stones, oil slip stones, and diamond slip stones. I own several water slip stones, which come in a long cone-ish shape (see above) and can be specially modified to help you get into the various parts of a moulding plane iron or other blade. Like with honing stones, I would recommend that you start out with three grits: 1,000 / 4,000 / 8,000:

You can purchase these slip stones at Lee Valley tools (here).  Norton also makes slip stones (find them here), but I have not used them. However, their waterstones are high quality, so I’m sure their slip stones would work just as well.  Ceramic slip stones are another option (I own some), and they work fine for honing moulding planes. I use them alongside my water slip stones, but they may not be necessary.

I purchased this Spyderco set on Amazon, which comes with 4 shapes and a leather pouch. I’ve found these files work just fine.

Buy or make a Leather Stop

Stropping a woodworking wood chisel on a leather stop

As I mentioned earlier, taking an extra step beyond honing can give you an even sharper edge on your hand tools, and keep you from going back to the honing stone. This is stropping on a leather strop. I make leather strops for my school using scrap leather glued to scrap wood. I then rub fine buffing compound on the leather, and have students rub the tool bevel on the leather stop every 2-3 minutes of work.

Using the rough side of the leather gives a better way to hold the compound. If you want a second strop for extra, extra fine stropping, then you can make a strop with the smooth side of the leather facing upward. If you can’t get down to the shoe repair shop to buy scrap leather, then you can just buy this leather strop and compound here on Amazon…actually, it’s cheaper than the shoe repair shop in my town. You can just glue it to a scrap piece of wood, and you’ll be ready to strop!

Buy a Diamond Lapping Plate

If you decide to purchase waterstones or oil stones, you will need a method for flattening them. You can certainly flatten them using sandpaper on a flat surface, but you will burn through a lot of expensive sandpaper, and the grit will continually gum up the sandpaper. One product that I now use quite often is a diamond lapping plate. I own the DMT DIA-FLAT Lapping Plate (purchased here) for around $165. A lapping plate can quickly and easily lap my waterstones and oil stones flat, which is vital for properly sharpened chisels and hand planes.

UPDATE: My neighbor recently told me that he used to lap his waterstones on cinderblocks. I’m not recommending or dismissing this method, but I’m intrigued to see how well it would work. I think I’ll try it out on a cheap stone first. Let me know if you’ve had success with this method.

Buy a Side Clamping Honing Guide

Honing guides are used to hold chisels and handplane irons at a consistent angle for honing. In many situations I have moved to honing freehand (because it’s faster), but when I sharpen certain hand planes for classes, I use a secondary bevel (specifically when I want consistent camber). For this a honing guide is much easier.

Veritas honing guide

The great news is that you don’t need an expensive honing guide. I often have students bring in their very expensive honing guides to class (like this Veritas honing guide and this Lie-Nielsen honing guide), but I have used a couple very simple and inexpensive ($10-$20) honing guides for years, with great success. Actually, I got one of my honing guides at a tool swap for $1 and I love it!

About 8 years ago I purchased this Robert Larson Honing Guide and it has worked just fine. Just make sure to use a properly sized screw driver, so you don’t strip the screw head.

If you want to see a broad range of other honing guides that are available, check these honing guides out at Highland Woodworking.

Buy a Card Scraper Burnisher

A cabinet scraper (i.e. “card scraper”) helps you to finish difficult surfaces that you may not be able to get smooth with a hand plane. Curly maple or other figured woods are a good example. You can learn how to sharpen a card scraper by watching my video tutorial of Elia Bizzarri teaching how to sharpen a card scraper (here). A burnisher is a steel rod used to harden the card scraper edge, and create a folded micro edge. Don’t try to use a screw driver. Instead purchase a dedicated burnisher. I purchased this Crown Burnisher on Amazon (around $20) and have found it to be satisfactory. Compare prices on card scrapers with these on Highland Woodworking.
