#1 - Arnold .065-Inch Maxi-Edge Commercial Trimmer Line

Arnold .065-Inch Maxi-Edge Commercial Trimmer Line

This 220 feet cutting buddy may be very affordable but it was not made cheap. It has a multi-sided edge (6 point star to be precise) which helps gardeners achieve that perfect cut. It reduces work time because you no longer have to go back and forth to ensure the cleanliness of your work.

Whether you have a gas or electric trimmer, this product is compatible. It has a diameter of 0.065 inches which enables you to do your residential jobs with ease. What I also love about this is that a single package contains 11 refills already. You do not have to put many spools in stock.

Lastly, you do not even have to bring your scissors with you as you use it because it has its own cutting tool.

Unfortunately, this is not the best trimmer for those who are always in a hurry because it may take time winding. Also, jamming and breakage can happen if this is not properly done.

What we like:

  • 6 point star multi-side line
  • Universal
  • Compatible for gas and electric trimmers220 feet long
  • Cutting tool included

    What we don't like:

    • Winding can be complicated for some, if done improperly may cause winder to jam

    #2 - BLACK+DECKER AF-100-2 30ft 0.065" Autofeed Replacement Spools, 2-Pack

    BLACK+DECKER AF-100-2 30ft 0.065

    This product is compatible for most Auto Feed System string trimmer models. This means that if you only have time to trim and not to wind your strings to your equipment this product is perfect for you.

    Aside from the fact that this trimmer is manufactured by a trusted cleaning companion brand, Black + Decker, you can be sure that this will be another high-quality product. The strings are clear or transparent which can be both a pro and a con. Pro since it is neat but sometimes it can also be a hassle when it comes to locating them.

    The concern that could come with this product now is that since it is autofeed, you cannot control the length of the string you would be using every single time. There is a possibility that you will just be surprised that it is all used up already.

    What we like:

    • You do not hand wind them!
    • Factory wounded
    • Auto feed system trimmer compatible
    • Uses centrifugal force

      What we don't like:

      • Maybe too tightly wounded
      • No control

      #3 - BLACK+DECKER AF-100-3ZP 30ft 0.065" Line String Trimmer Replacement Spool, 3-Pack

      BLACK+DECKER AF-100-3ZP 30ft 0.065

      If you want to have the perfect cut for the grass in your lawns but in need for a string trimmer refill, I highly suggest this product. It has a diameter of 0.065 inches, perfect for light works. This line string is clearly colored making it look classy but it is really affordable.

      On top of that, this spool is factory wounded. It gives gardeners ‘maximum reliability’ as per the words of the manufacturers. If winding has been a personal struggle for you, this is the right product for your Auto Feed System string trimmer. All you have to do is to install and then trim. It uses centrifugal force to help you perform faster.

      It is compatible with different models and it has a two-year warranty. What more can you ask for?

      You may have noticed that I also have another Black + Decker item, I am including this item since it can give you more value for your money when you buy a pack of 3 string trimmer lines. Nonetheless, they share the same issue of users not being able to control the length of the line being used.

      What we like:

      • Packs of 3sUses centrifugal force
      • Factory wound
      • Compatible with many string trimmer models
      • 2 years warranty
      • Perfect for Auto Feed Systems

        What we don't like:

        • Automatic – length or usage cannot be controlled

        #4 - Cyclone .155-Inch-by-315-Foot Commercial Trimmer Line, Red CY155S3

        Cyclone .155-Inch-by-315-Foot Commercial Trimmer Line, Red CY155S3

        Since this article is for gardeners from all walks of life, this is the best product for those who own vast areas of garden and for those who are planning to use the spool in industrial areas.

        Cyclone .155-Inch-by-315-Foot Commercial Trimmer Line is highly recommended if you want fine chopping done in a shorter amount of time. It has this patented 6 bladed shape that gives you powerful cuts in one go. Unlike others with a rounded shape, you have to carefully adjust and readjust the height to get even cuts in one sweep.

        That means that you do not have to go back and recut again and again. This is also recommended for gardeners who have high-wheel trimmers.

        Since this is made for commercial purposes, the material used to create Cyclone Trimmer Line is copolymer nylon.

        With all of these benefits, the product has to offer, you may expect that this is actually the most expensive item in the list but it is all worth it.

        What we like:

        • Patented 6-bladed shape
        • Made of commercial grade copolymer nylon

          What we don't like:

          • Expensive
          • Confusing as some labels may say .155 and 0.065 inches

          #5 - Worx WA0010 Replacement 10-Foot Grass Trimmer/Edger Spool Line, 6-Pack

          WORX WA0010 Replacement 10-Foot Grass Trimmer/Edger Spool Line

          For more controlled use of your trimmer line, go for Worx WA0010 Replacement 10-Foot Grass Trimmer. You can never go wrong because it is packed with 10-foot line per spool.

          It is made of copolymer nylon resin which makes it extra durable but light. It has an aerodynamic shape which will help you achieve a clean cut at a faster rate. I like the fact that it has a tensile strength of 100 pounds. This means that it can cut more effectively to harder and thicker weeds or grasses than the others.

          The string is also versatile and stretchable. This helps provide the string to have a longer lifespan and it does not easily damage hard surfaces. Ill-advisedly, some models may not fit as this is a cute small sized spool. Please check the models for compatibility carefully before buying.

          What we like:

          • 10 feet long per spool
          • Made of polymer nylon resin
          • Multi-sided
          • 100-pound tensile strength

            What we don't like:

            • Maybe very small for some models

            Things to Consider when Buying Trimmer Lines


            Please do not get me wrong, all of these factors are highly important. But for a time-conscious individual like me, I honestly do not want to go through other details without assuring that the trimmer line is actually compatible with my string trimmer unit.

            It just won’t make sense when you go through all the other details only to find out in the end that it is not the right fit for your equipment, isn’t it?

            Durability and Materials

            A durable trimmer line will save you time, money and effort. You can just imagine changing it from time to time even after minutes of usage. Get a line that could serve you for a long period of time.

            Your string line can be made from different materials. Nylon can go a long way for you, for example. It is light and readily available on the market. Few users, on the other hand, prefer the more expensive and sophisticated titanium string trimmer. This is a very powerful line that we should all be expecting to roar soon.


            Now you may be wondering why diameter is an issue discussed separately from compatibility. Yes, it is one of the things you should check for to know if it is well-matched but there is more than that. The diameter will tell you what kind of work you should be doing with the trimmer line that you have.If you are making use of your string trimmer for the upkeep of your residential garden, the perfect diameter for you is 0.065 to 0.080 inches.

            If you need to deal with more complex weeds or a lawn that is bigger, consider getting 0.085 to 0.105 inches. 0.110 inches and bigger are suggested for vast gardens and industrial settings such as golf courses.

            Knowing this will definitely prolong the lifespan of your product.


            Apart from what most people know, there are also different kinds of trimmer line shapes. Yes, I am not kidding! You can select from multi-sided, rounded, serrated, square and twisted. It will depend on where you will be using it, nonetheless.

            If you have high-wheel trimmers, large area, and thick weeds, you should buy the multi-sided line. This gives the cleanest cut of them all. The most common shape of all is circle. You can have another option if you have the similar situation and that is the serrated trimmer line. You can surely get quick and pristine cuts with this two. With its sure edges, a square line is the best bet for heavy work. It is the toughest, rigid, and cuts faster.

            A rounded trimmer line is for smaller areas and lighter cutting tasks. Apart from that, it is easy to find. Twisted trimmer lines are highly suggested for industrial use, or simply when you get irritated with the noise the tasks produces. What I like about this shape is that it is more robust that the rounded one.


            Do not waste your time further by using ineffective trimmer lines. Get the one with the highest quality so that you can easily and effectively beautify your gardens.I gave a 5-star rating in this best trimmer line reviews to BLACK-DECKER-AF-100-2-Autofeed-Replacement. You can get it in a set of 2 or 3s whichever is perfectly fitted for your budget.

            Based on our discussion above, I consider this the most excellent product because it is perfect for household landscaping. I love that it is factory wounded. It is very easy to use that I do not even need the help of my husband to install it. It fits perfectly in most string trimmer heads.

            It is compatible most especially to trimmers that have auto feeding system – which people who are always on the go are using.

            It is light, it has a clear color and the diameter is round. This is just the perfect tool for light works and small to medium size gardens. It is very practical not only because it has a 2-year manufacturer’s warranty but simply because it does not easily wear compared to others which also has a round diameter.

            It is just very important for you to know how to properly assemble the product or else it can get tangled, broken and it can jam the equipment if instructions were not properly followed.

            Thank you so much for reading this article. I hope I was able to help you. Please do not forget to share!
