Self-Sharpening Chainsaws: What you may want to know?

There is no doubt that chainsaws are the most reliable cutting tools available to any lumberjack. When new, some of them can cut through any toughest wood thrown at them. However, after some time, the cutting edge becomes somewhat blunt. If you find yourself putting more pressure on the chainsaw than usual, then it needs service.

The most probable solution is sharpening the teeth. But how do you do that? Well, that depends on the type of chainsaw you have. Whichever tool you will use will be determined by several factors, including the size of the teeth. Others can self-sharpen, and these are the focus of our article today. Let us first look at some of the common sharpening techniques.

Self-Sharpening Chainsaws

Common Chainsaw Sharpening Methods

File Sharpening

One of the most popular methods is the use of a file. To achieve the task, you will need a specially made file, usually round, and a file guide. The work of the file guide is to ensure that you maintain the correct angle. Why should you do that?

Every chainsaw has a specific sharpening angle which will ensure uniformity across all the teeth. It can be anywhere between 25 and 30 degrees depending on the saw’s manual. Failure to comply with this might have serious repercussions, and you could find yourself buying a new chain.

One obvious disadvantage is accuracy since you will be majorly relying on your intuition. Another one is, of course, time and energy. Unless you have enough time, this might bring a lot of inconveniences to your plans.

Electric Sharpening

This category is further divided into two; portable and mounted sharpeners. For a portable electric sharpener, you can hold it in your hand and complete the task. It is most suitable for those who are always on the move. Mounted ones can either be fixed on a table or the wall (consider where it is convenient for you).

This technique is way better and faster than the previous one. As stated before, accuracy is key when it comes to sharpening, and mounted electric chainsaw sharpeners provide that. Also, it is not as time-consuming as manual sharpening.


This is the third method, but it is not quite popular despite being in existence for over 50 years now. It was invented in the 1960s, and new chainsaw models featuring this technology were released around the same time. Since then, it has been an up-and-down ride in the market.

These models have never gained massive popularity like the rest. Some of the reasons could be the inferior saws and less effective parts attached to them. But there have been a lot of improvements over the years to be able to attract more users. The world’s well-k known brand, Oregon, is one of the leading pioneers of the self-sharpening saws.

If you are one of those who find manual sharpening as a brutal chore, then you only have two choices; an electric sharpener or a self-sharpening chainsaw. An electric sharpener requires additional equipment, another reason why some people prefer self-sharpeners.

The Original Self-Sharpeners

In the 1960s, the world of wooding was introduced to a whole new product. However, the new models of chainsaws that had this new (at the time) technique did not live up to expectations. The first ones to be released had a sharpening stone attached to the clutch cover. The idea was that this stone could be applied to the outside of the blade and as the chain ran past it, the teeth would be sharpened.

Fast Forward…

Recently, Oregon and other manufacturers within the industry came up with a much-improved technology. Here are some of the best self-sharpening chainsaws currently in the market.

If you are looking for the best in this category, then not many chainsaws beat the ability of PowerNow. It comes with an advanced battery technology that ensures better and uninterrupted performance. PowerNow also takes the least time possible to start up.

The powersharp system (Oregon’s self-sharpening technology) ensures that your chainsaw is always up to the task. The lever included helps you control the system and adjust it to the desired functionality. Once you have activated the lever, the system automatically sets ideal angles and starts the process when the chain is running.

Another product from Oregon that has gathered a host of good reviews is the CS1500 self-sharpening chainsaw. This is one of the best electric chainsaws by It comes with an 18-inch guide bar and chain. Both of these cutting equipment (chain and bar) is, of course, from Oregon. The chisel-style cutters never disappoint when it comes to woodcutting. Initially there was a common complaint from users about the falling of the chain, which would sometimes be extreme. This was, however, resolved by the manufacturer and things look great at the moment.


Currently, there are few reputable self-sharpeners in the market because currently not many users fancy them. Oregon and a few other interested manufacturers have continuously made improvements to the existing chainsaws. The fact that these models keep coming and going means people are slowly starting to realise the significance of automatic sharpening. As such, you can be sure that their popularity will hugely rise in the coming years
