Things to Consider before Buying Weed Eater String

So, now you know what string to choose when you are looking for the best weed eater string. But that is just a list based on our experience and final decision. It means that you may also have your own choice and preference.

It is not a must to choose one of the products we listed. However, you need to follow a specific buyer’s guide to help you find the best string for your weed eater.

Here is a look at the things we considered when listing the top 10 strings for string trimmers:


You should know that a trimmer line will come with a specific shape. While this might not seem like a priority, it is one of the top factors you must consider.

Most of the trimmer lines out there come in a round shape. However, this type of line doesn’t have the best cutting ability. Plus, a round-shaped line won’t distribute force accordingly. They also tend to snap too often.

For a reliable line that cuts effectively without multiple changes, opt for a multi-sided line. We will cover more about the shapes of the weed eater strings later in this article.


The durability of a weed eater string is a top factor that you must consider. This is a general for any product you purchase out there. Even when and if you are buying a weed cutter, you will need to consider one that is durable enough.

You don’t want to use a product that will only last for a few weeks or months; then it breaks down. Instead, you need to choose one that lasts for long enough to avoid overspending.

So, when it comes to the durability of the product, you must choose one that is made of high-quality material. The shape of the line is not enough to prove if the trimmer line will serve you effectively or not. Look beyond the shape and consider one that is sturdy and durable enough.

Ideally, avoid going for simple plastic trimmer lines. So, which is the best material for trimmer lines? Well, the sturdiest material, which is generally the best, is copolymer nylon. This material is strong and durable enough. You can be sure of a copolymer nylon trimmer line being able to slice through the toughest greenery.

With the cheap plastic line, they might only slide on the thick greenery, which will be a waste of time. That is why you must ensure that the trimmer line you get is made of high-quality copolymer nylon.

By the way, you can find some lines coming with dual cores; the inner core and outer core/layer. Such lines are usually solid and overly durable.


A lot of the plastic weed eater strings are ruined in hot environments. Here is when they tend to weld. But not all weed eater strings are weld-prone. Some are strong enough to resist welding.

Welding can be frustrating when it happens to your weed eater. When it happens, it can be frustrating and generally difficult to separate the lines from each other. In turn, this will make it challenging to load the weed eater.

To make it worse, the line can weld together inside the string trimmer’s head. This is a common issue on hot days, which can prevent the trimmer from dispensing the string.

For that matter, you will need to ensure that you find a high-quality weed eater string that will last for long and withstand the hot days. This is a must-do for those that live in places that it’s always hot. Here, the best choice should be nylon polymers since they are sturdier and heat-resistant.

Also, star and square-shaped lines tend to perform better in such situations.

Flight Characteristics

When picking a line for your string trimmer, you need to remember that it is flung through the air before it gets it to contact with the grass or weeds. In this case, you must consider the flight characteristics of the line.

That being said, always ensure that you choose a trimmer line with lower air resistance tends to be the better option. This is because they will make your string trimmer work less hard hence preventing the wear of the machine. Square lines are less aerodynamic, while round and oval lines are more aerodynamic.

Furthermore, consider the level in which the string sits while you cut the weed and grass. Suppose the string is uneven; it might not cut the grass and weed effectively.

Weed Trimmer Line Shape Types

When it comes to the shape of the trimmer line, you should know that there are multiple shapes out there. We have mentioned a few of them, but it would be better if you knew how they work and which shape of the trimmer line is suitable for you. Here are the typical forms of weed trimmer lines:


Round trimmer lines are usually basic and considered all-purpose strings. Most of the weed eaters designed for home use come with a round trimmer line. One benefit of the round lines is that it cuts decently, and it isn’t prone to breaking off too quickly.

So, if you want to cut the household weeds and grass, a round-shaped trimmer line shouldn’t be a bad pick.

Besides the round trimmer lines, you can find those that are multi-sided. Most of the multi-sided lines come with five sides or more. They are also called star-shaped trimmer lines, and they are best suited for medium to heavy-duty jobs. With the multi-sided weed eater strings, they deliver a cleaner cut on the thick greenery.

Nevertheless, multi-sided lines tend to be extra fragile. They can break off when they get in contact with a hard surface. Also, these lines are mostly used in commercial/professional landscaping.

Twisted/X Lines

You can also find twisted lines, which happen to be strong and perfect for heavy applications. However, they also come with a high price tag, which you should be prepared for that.

Besides offering a sturdy and robust cutting opportunity, these lines minimize the vibrations as they rotate. These lines are also suited for commercial and professional landscaping.


If you are looking for a string that can handle medium and heavy-duty applications, a square-shaped string line would be an ideal pick for you. Square-shaped lines can easily cut through thick greenery compared to round lines.

However, they are prone to breaking off if they get in contact with hard surfaces like wooden fences, trees, or shrubs.

Jagged/Serrated Lines

The last type of trimmer line shape is the jagged or serrated line. These types of lines are serrated like a saw. Out of all the weed eater shapes, the serrated-type has the best cutting power. It cuts quicker than any other line out there.

Plus, it will snag on the thick greenery to make it easy to cut them down. Nevertheless, the serrated trimmer lines tend to require more energy because they ‘hold’ on to the thick weed and grass.
