Chainsaws are powerful tools used by both professionals in the logging industry and people at home looking to do a bit of landscaping. They can be powered by an electric motor or a two-stroke gasoline engine.

While chainsaws are extremely effective, regular maintenance is required to keep your chainsaw in good working order. In this article, we will be taking a look at the Granberg Bar Mount Chainsaw Sharpener - a simple tool that is crucial for keeping your chainsaw sharp at all times.

About the Granberg Brand

The Granberg International company traces its history to the forests of the Pacific Northwest, where in 1954, a WWII veteran and logger named Elof Granberg was working.

Realizing that traditional freehand chainsaw sharpening was inaccurate and time-consuming, Elof would set out to change things. He did so by first inventing the File-n-Joint, a simple handheld chainsaw sharpener that could be attached to the guide bar of the chainsaw.

This innovation made chainsaw sharpening significantly easier and cut down time wasted on sharpening the device. Building upon this success, Elof would go on to purchase the rights to a bar-mounted chainsaw mill, affectionately known as the “Alaskan.”

By putting together his love for innovation and the credo of “working smarter not harder,” Elof would further improve on the design of the “Alaskan” and it goes without saying that his efforts have paid off.

This is because the Alaskan MKIII is widely recognized as one of the most effective chainsaw sharpeners and is widely sold all over the world.

Even after more than half a century in operation, Granberg International is still an industry leader. Elof’s descendants have gone on to manage the company and bring it to new heights.

All of Granberg International’s products adhere to the credo of being affordable, accurate and well-designed, with all products made and assembled within the United States.

The Granberg Bar-Mounted Chainsaw Sharpener Model G106b is widely recognized as being one of the most cost-effective chainsaw sharpeners on the market.

Essentially, the G106B is attached to the guide bar of your chainsaw and it allows you to sharpen the teeth of your chainsaw without removing the entire chain. This cuts down on time required to remove, sharpen, replace and adjust the chain.

While it may not be the easiest device or the prettiest looking tool on the market, you can rely on the G106B to get the job done in even the harshest conditions.

Users of the G106B have noted that it provides even, consistent sharpening, which ensures the effectiveness and longevity of the chainsaw. One should not expect less from a company like Granberg, with a reputation for building precise, well-designed tools.

One of the stand-out features of the G106B is the fact that it does not require electricity to work. In fact, it does not require any additional accessories or tools to work. All you need to do is fix it on and away you go.

This makes it extremely useful for situations where you are working deep in the sticks with just your wits about you and little else.

Ease of Use

chainsaw sharpening review

Some users may be more familiar with bench-mounted electric chainsaw sharpeners, but the G106B is a manual sharpener that was designed more than 50 years ago.

Given its old-fashioned design, chances are high that some users may struggle with it at the start. True enough, other reviewers have stated that the G106B’s archaic design and absence of instructions make the tool difficult to use for inexperienced chainsaw operators.

Another complaint with regards to this sharpener is the length or the lack thereof in the handle, which forces users to wear gloves in order to get a good grip. Also, it has been noted that the G106B has to be continually adjusted, as the jig has a tendency to sag.

While the G106B may not be the easiest to use at the best of times, using it is a simple affair once the operator familiarizes himself or herself with the tool.


As anyone who works with a chainsaw can tell you, keeping your saw sharp at all times is crucial for a consistent and safe performance. However, keeping your chainsaw sharp at all times can be a challenge without access to the right tools.

This is where the G106B shines through, thanks to its light weight and small size. Weighing in at only 2.0lbs, you can easily pack the G106B in your field kit without having to worry about breaking your back.

Its small dimensions make for easy transport and ensures that it does not get in your way.

Build Quality

The G106B is a sturdy device that is built from pressed aluminum, which eliminates the risk of rusting. Also, there are no cheap plastic components present and all connections feature thumbscrews or wingnuts.

This means that there is no need to worry about Allen Keys or screwdrivers. However, all of this does not mean that you can treat your G106B like a Mack truck, as there have been complaints about the flimsy jig and the pressed metal screws.

That is why for the best possible performance, store your G106B in a sturdy case where it won’t get knocked around or bent out of shape.


Overall, the G106B is a sturdy and effective chainsaw sharpener. The fact that it does not require a power source makes it especially appealing, as it allows you to sharpen your chainsaw anytime and anywhere.

Unfortunately, the tool is less than user-friendly and can be difficult to handle in the hands of an inexperienced user. However, with time and practice, the G106B can be an invaluable part of your toolbox.
