There are few things more frustrating than a chainsaw that won’t cut. Even the best quality chains inevitably become blunted by prolonged use. Though the effect of your saw’s chain becoming duller might not be noticeable at first, as this process continues, you will find it harder and harder to make the cuts you want.

The obvious solution to this is to buy yourself a good quality chainsaw sharpener that will allow you to keep your blade at the very peak of its cutting power. As with any product in this day and age, there are lots of good designs out there, though these differ quite considerably.

Since tools are designed to make our lives easier, it is important to always have the right ones in your tool bag for when and where you might need them. There is a surprising amount of variation in chainsaw sharpener design. Some are designed to be used portable and used anywhere, while others are designed to make the job easier, but are not really portable. So to help you find the right one for your needs, we have put together a list of all the things you need to know when buying one, including a list of our top choice chainsaw sharpeners of 2017.

Why do I need a chainsaw sharpener?

Lots of people make the mistake of heading down to their local hardware store and buying the first chainsaw sharpener that they see. Since some chainsaw sharpeners work with certain types of saws better than with others, buying the first one you see can turn out to be a big mistake. If nothing more, this fact should certainly be enough to make you consider which model is best for a few moments longer.
The first part of this process begins with making sure that you have the right chainsaw for the jobs you use it on. A chainsaw with a long blade and chain, for example, will wear out slower than one with a shorter chain, purely because of how much extra work a shorter saw has to do to cut the same amount of wood.

Choosing the right chainsaw

The most important things you need to think about when buying a chainsaw are what kind of cutting you intend to do, and how much do you intend to use it. A great tip on choosing the right size is to buy a chainsaw with a blade that is about 30% longer than the thickest cut you intend to make. You should have a good idea of how thick the trees you will be cutting are, so if for example, you are cutting a tree with a 20-inch diameter, you should buy a chainsaw with a blade of 30 inches or more. Not only will having the right sized chainsaw help to prevent rapid blunting of the saw, but it will also enable you to make cuts faster and with more control as well.

How to make sure you get the best chainsaw sharpener

Lining your chainsaw blade are rows of teeth or cutters, which when the saw is in use, run down the saw blade and cut the wood. With each pass they slice out a small section of wood, which continues with each successive tooth. In order to facilitate this process, the blade has special ‘rakers’ which help to shift cut pieces of wood out of the way to allow access to the next layer of wood.

When it comes to sharpening the blade, it is the cutters that require the most maintenance. Individually filing each of the cutters on a chainsaw blade is certainly a time-consuming exercise. For a 30-inch saw, you could expect to spend anywhere in the region of one to two hours to make sure that you get the job done right when using a simple file. Since few people would ever consider this to be fun, it is much better to use a specialized chainsaw sharpener that will do all the hard work for you.

One type of chainsaw sharpener uses an electric motor to spin a grinding disk that individually sharpens each individual tooth. The whole mechanism is adjustable, so it can be used on a whole variety of chains. You will need to have a good idea of your chain’s optimum tooth angle before you set your chainsaw sharpener up, but once you have done so, the sharpener will do the rest for you.

The other main type of chainsaw sharpener uses a special clamp unit to clip onto your chainsaw’s guide bar, after which it sharpens the teeth as you manually feed the blade through. It requires human power to draw the blade through and to operate the tooth sharpening mechanism also. This process is certainly more time consuming and much harder work than with the electric motor models, but is certainly still a lot better than using the old hand files. The other benefit of this kind of sharpener is that they are less expensive and more portable that their motor driven counterparts.

The importance of good maintenance

Chainsaw Sharpener - MaintenanceMaintain your chainsaw well and you won’t need to sharpen your blade as often, this is the golden rule. Before you begin any cutting, you should check the saw blade to make sure that it rotates properly and is free of any severe rust patches. Then you should generously apply a good quality chain oil to help minimize the amount of damage from wear. To do this, apply the oil to the top part of the blade and gently rotate the blade as you go. This is the best way to ensure that no part of the blade is missed and to make sure that the oil seeps down onto all parts of the blade.

At this time, you should also check the tension of the chain on your saw. Due to the stresses and strains that they are placed under, chains lose their tension over time and so need to be tightened regularly. A loose chain will increase the rate at which the chain degrades and also increase the chance of it jamming, something that could cause a lot of damage.

Taking good care of your engine is also very important. Be sure that in the case that your chainsaw is gas powered, to make sure you are using the correct gas to oil mixture. If you run the engine too lean (not enough oil in the mix), then you run the risk of wearing your engine out much quicker than would otherwise be expected. Your chainsaw’s instruction manual will tell you the exact ratios it requires, but the general rule is five ounces of motor oil per one gallon of fuel.

A nice and sharp chain will reduce the chance of any accidents or kickbacks. It will also increase the life of your chainsaw engine by reducing the higher revs that are required in order to cut with a blunt blade. To make sure you keep your blade as sharp as it can be, you only need to buy a good quality blade sharpener and you will never have to worry about having a blunt saw ever again.

Price is always a factor, so after you know what you want, you should see what is available and within your budget. Don’t buy the cheapest one just to try to save money, as you might well find yourself paying more in the long run, because as the old saying goes, “I’m not rich enough to buy cheap clothes”.

Instead, search for the best products that fit your requirements and then start to factor in the price to see what the best one really is.
