Maintenance is inevitable even for the most high-end chainsaws. Otherwise, they become unsafe and hard to use. However, no one wants to sharpen the multiple chainsaw cutters with a file because this process is really time-consuming and tedious. Sharpening services offered by hardware stores can be quite expensive. Hence, choosing and buying the best chainsaw sharpener may be a good alternative.

At first sight, many devices seem to be too similar or, on the contrary, too different that complicates the choice for an inexperienced user. I have collected a diverse selection of products that feature different designs but offer the same level of quality. The article showcases the features of each product, including their advantages and disadvantages, in order to provide an honest and comprehensive evaluation of their value. One can find here both manual and electric sharpeners that will become a good addition to your kit. I hope that my product comparison will assist you in determining whether or not these items are worth the investment.

Katzco KCO — Best chainsaw sharpener file set kit

Katzco KCO
The device is among the most remarkable chainsaw sharpening kits, featuring 8 pieces for many applications. The set includes 3 round files (3/16, 5/32, and 7/32), a 7.75-inch file holder, a 6-inch square one for filing and cutting, and a 4-inch hardwood handle. The latter is compatible with the pieces from the kit and other manufacturers’ files. It should be noted that using it requires some effort when filing. There is also a 7-inch depth gauge in this pack. It helps set the right rake tooth height regarding the cutting tooth height.

The kit can be considered to include the best chainsaw files since all the pieces have excellent quality. They maintain the blades well, keeping them operating with maximum performance. The guideline assists in establishing the correct angle.

This item can be applied to any chainsaws, cutting their teeth at a 90 or 45-degree angle. All the files are easy to attach and remove. The kit is enclosed in a red soft case that has compartments for each piece. This roll-up solution makes the kit portable and convenient to carry around. The entire package measures 3 x 1 x 2 inches and weighs 8 ounces.


  • The device generates no heat, thereby keeping the cutters cool during sharpening.
  • It works fast, taking nearly half a minute for every cutter.


  • The instructions include technical terms that might be difficult to comprehend.
  • Some files get loose and slide out from the handle.

Oregon 617067

Oregon 617067
The Oregon chainsaw sharpener is a relatively small roll-up pack with 7 hand tools that comes in a fabric cover. It provides users with a 6-inch square file, 0.156-inch, 0.187-inch, and 0.218-inch round ones, and a versatile handle. Those who consider buying the packs with chainsaw sharpening guides may appreciate its convenient metal guide to check the raker height. The dedicated lines on it enable precise alignment. It was a nice surprise to see that the depth gauge tool for the consistent setups is also included. The handle enables quick removal and insertion of files while securely holding them in place. As for the round file, it looks like it’s made of soft metal. I guess I will have to replace it soon.

The chainsaw sharpener kit matches full-comp and semi-skip chains with a 0.375-inch low profile, .325-inch and .404-inch pitches with any cutter sequence. The 617067 is relatively fast, making approximately 40 cuts per hour. It weighs 12.3 ounces and has 2 x 10.8 x 2 inches in size.


  • The raker gauge operates flawlessly.
  • Judging from the quality of the steel used to manufacture the square file, I believe it should provide long-lasting service.


  • The kit is useless for square ground cutters.
  • Defining the directions is challenging.

Stihl 325 — Best rated chainsaw sharpener

Stihl 325
The metal Stihl chainsaw sharpener suits a .325-inch pitch, operating at 25–30 or 90 degrees from the bar. The “arrow” symbol is printed on one of the sides showing which direction the file should be moved in. The sides of the device are angled at 30 degrees.

When I lifted the item, it felt relatively heavy. In other words, this is not just a cheap piece of plastic — it should serve you for years. It also features a simple file replacement process: you just need to press a button to open one side.

This product may become the best chainsaw sharpener due to its solid construction that includes 3 files. Two of them are round, and the other one is square to work at precise angles. The item is equipped with 4 square rails, having two of them on each side. They are made to ride on the two teeth (front and back), as the operator is cutting them. Remember to maintain the proper file depth during use.

On putting the 325 on the scales, I’ve got the same weight as the manual specifies, namely 12.3 ounces. The claimed dimensions of 8.43 x 1.96 x 0.91 inches are correct. The instruction manual for this model is exceptionally clear, consisting solely of pictograms without any written instructions. It means no matter what language the users speak, they will figure out all the details easily.


  • The unit can become the best chainsaw sharpener, as the tool cuts like a brand-new product after proper maintenance.
  • The 325 leaves no damage on the cutters and doesn’t deform the chain hooks.


  • No additional items are included in the pack (I’d like to see spare files, for example).
  • Increasing the size of the handle would enhance its convenience.

Stihl 3/8 P

Stihl 3 8 P
The metal Stihl 2-in-1 chainsaw sharpener is produced for a full house chain, also working with the skip one. You can use the device out-of-the-box with no need for file assembling. The package includes a couple of 0.156-inch files to work on the STIHL 0.375-inch PICCO chains and other brands’ 0.375-inch low-profile ones. The pack has replaceable round (1) and square (2) files, located between 4 rails. The tool has arrows that indicate the proper grip and motion. It is recommended to flip the unit over when filing the other half of a chain.

The 3/8 P performs 2 functions: it resharpens the cutters and files down the depth gauge. Bear in mind that the 3/8 chainsaw chain sharpening angle should be at 30 degrees with a depth gauge of 0.20 inches. The gadget maintains a consistent angle and sharpens down the gauge simultaneously. However, it requires a clean bar to ensure the expected outcome. Otherwise, the teeth will remain blunt. The tool has a weight of 14 ounces and dimensions of 16.54 x 1.97 x 1.18 inches.


  • The entire filing takes no more than 20 minutes, requiring from 3 to 5 strokes per tooth.
  • The 3/8 P doesn’t bind in the tooth.
  • The tool is user-friendly, even for beginners.


  • The angle does not perfectly align with the cutter’s edge.
  • The handles don’t allow using the unit’s full length.
  • It’s challenging to get the file for the rakers when replacing it.

Oregon 410-120 — Best electric chainsaw sharpener

Oregon 410-120
The Oregon 410-120 is a professional and versatile assembly for both regular and high-volume use that helps maintain the equipment of numerous manufacturers. It works on 0.250-inch, 0.375-inch low profile, 0.325-inch, full profile 0.375-inch, and .404-inch pitch chains.
Featuring an impressive build quality, the device measures 15.25 x 11.8 x 8.6 inches and weighs 17 pounds. Its top and the black-colored part are made of cast metal. All the handles appear to be durable as they are constructed from sturdy plastic material. The design of this electric chain saw sharpener is well-considered and straightforward, enabling the user to adjust the head angle and move the chain forward or backward.

The degree scale with legible marks helps set the required angle easily. Just loosen the clamp on the rear part of the grinder’s head bracket and set the head into the appropriate position. Moreover, setting the correct angle is not a problem due to the detailed guide included in the package.

This model makes any job safer. It has a built-in light on board to work in poor lighting conditions effectively. Its safety shield protects the user against the finest particles of the grinding wheel that usually come away during the operation. The one-way motor disengages torque transmission if the device begins to operate in reverse. The dedicated indicator to notify about the need for wheel replacement is included. In this case, consider using only the 7/8-inch arbor wheels with round-shaped openings for screws.


  • There are 3 spare wheels in the pack.
  • The grinder can be mounted on a workbench or wall.


  • The unit can be integrated with the full-sized wheels, but the 0.4-horsepower motor with 3150 RPM lacks power for them.
  • The instruction manual is not clear enough to facilitate an effortless setup of the tool.

The chains gauge should be in the range of 0.05–0.08 inches.

It’s easy to start working with this electric chainsaw sharpener since it comes entirely assembled. The only operator’s task is to regulate the angle. A dedicated adjustment screw is available to establish the correct angle for sharpening. Another adjustment screw is on top for loosening or tightening the angle based on the desired head’s position. The dedicated fin is used to reposition the chain, providing access to its other cutters. A small screen, made of transparent plastic, protects the user from sparks. The entire construction is lightweight (4.11 pounds), having 13.5 x 9.5 x 6.25 inches in size.


  • It fits the common chain modifications.
  • The metal parts, despite being limited in number in this model, are resistant to rust.

Oregon 575214 — Best 12v chainsaw sharpener

Oregon 575214
In my chainsaw sharpeners review, I cannot miss a portable electric Oregon 575214 with 0.156, 0.187, and 0.218-inch grindstones. A collet, working as a wrench and a screwdriver at a time, is also in the pack to tighten or loosen the stones. The guide for angle regulation has 25, 30, and 35-degree markings and is easy to understand. The item fits plenty of chains up to .404-inch pitch. It is noteworthy for its 55-Watt powerful motor, capable of 25,000 RPM.

The model can be connected to a car outlet and features clamps to draw power from the car’s battery if needed. That’s why the 575214 can be considered the best chainsaw sharpener for occasional maintenance during cutting somewhere in the field. Of course, regular work requires a stationary bench or wall-mounted equipment. The compact items’ dimensions are 5.6 x 10.2 x 2.5 inches and it weighs just 1 pound.


  • The item features a relatively long cord of 29 inches.
  • Additional grinding stones are included in the package.


  • There is no option to set the depth gauge. For this purpose, the user has to buy the square file and drop-center depth gauge tools separately.
  • The wrench screwdriver’s end is too thick to fit the guide screw.

Granberg G106B — Best bar mount chainsaw sharpener

Granberg G106B
The Granberg G106B stands out from many bar-mount chain saw sharpeners accessible on the market today. This robust unit is constructed of zinc-plated steel and cast aluminum, providing long-lasting performance for many years and excellent resistance to rust. There are no flimsy elements in this model at all. The equipment weighs 1.05 pounds, having the dimensions of 12.5 x 7 x 1.5 inches.

Besides, the unit demonstrates a consistent performance, working on the chain at a precise angle from 0 to 40 degrees without any shifts. The G106B processes both sides of the chain. To achieve this, simply loosen a pair of wing nuts and rotate them to 10 and 25 degrees on the other side of the dial.

The Granberg chainsaw sharpener is delivered completely assembled and is easy to use. It suits the bars of any length and all types of chains. It comes equipped with a screw that enables the user to adjust the height of the file. There is no need to change the tool’s placement for shifting a chain from one tooth to another. Still, the operators have to take the G106B from the saw’s bar and shift the chain manually. I would say that this process can be time-consuming. So, I’d recommend using a vise to speed things up a little.


  • It surprisingly not only sharpens the chain but also lowers depth gauges, equipped with the black round head with the spring for this purpose.
  • This tool ensures that all the teeth are the same length.


  • Additional files are not included with the product and must be purchased separately.
  • The steel handle has no covering. It is slippery and doesn’t provide a good grip.

Oregon 520-120

Oregon 520-120
This heavy-duty bench-mounted assembly is made with the claim on the best chainsaw sharpener. It has an enhanced chain vise that is crucial for those requiring plenty of sharpening to be done. The tool features a wide scope of applications, being suitable for all saw chains up to a 0.404 inches pitch. It has a smooth and elongated design that allows it to operate seamlessly by sliding back and forth. Additionally, the tool features onboard lights that aid in working in low-light conditions.

The unit is fitted with a direct drive one-way 0.4-horsepower and 4.3-amp motor. It has 300 watts of power that is enough to provide fast grinding.

This unit comes with all the necessary components (i.e., 4 and 5-mm hex wrenches) to assemble and set the sharpener. It’s equipped with grinding wheels that have a thickness of 0.125, 0.187, and 0.25 inches. Besides, they are sold separately. The entire construction appears sturdy, featuring a cast-aluminum chassis and a large motor fan with T-shaped fins for improved cooling. The latter is important to provide efficient cooling. The adjustable head also plays a role in improving the convenience of use, leaving more space for filing depth gauges. Besides, the manufacturers made a dedicated tripod stand to support the tool. However, it is sold separately. The unit itself measures 15.4 x 11.85 x 10.3 inches and weighs 19.36 pounds.


  • All the parts are well secured, which excludes the vibrations during the operation.
  • The wheel rotates away from the user to reduce the amount of shrapnel during the grinding process.


  • The mounting hardware is not supplied.
  • It would be great if this product is compatible with wheels larger than 5.75-inch in diameter.

When is it Time to Sharp the Chainsaw?

In the last paragraph of my chainsaw sharpener review, I’d like to point out the proper moment to maintain the chain. It is essential to note that the more powerful the saw, the more frequently it needs sharpening. Of course, it’s necessary to take care of the chain with every filling of the tank with gas, no matter how much the saw was in use. However, it comes with the preventive measures that require just a couple of strokes per tooth to bring the chain back.

It requires additional effort during the use to maintain sharp teeth at all times. So, never wait until the chain becomes completely blunt. Once the saw makes uneven cuts and pushes the wood away rather than cutting it smoothly, it’s time for sharpening. It’s quite dangerous to continue the work if much pressure is needed to make the saw go through the wood. Besides, dull chains output fine wood dust, while sharp teeth produce thin shavings. The smoke can also appear, even when the saw is oiled properly.
