Best Weed Eater Blades

by Dan | Last Updated: January 18, 2021

When purchasing a new weed eater blade, you’ll notice that there is a wide range of selections to choose from. Weed eater blades are categorized as either metal or plastic blades. In case you don’t know what each of these blades is best for, here is the information about each one of them.

Plastic Blades

They’re mostly used in trimming grass and weeds and are used as an alternative to nylon monofilament lines for cutting light weeds and grass. However, unlike nylon lines, these blades should not be used for edging or cutting through hard surfaces.

Metal Blades

They have chisel-shaped blades which are ideal for cutting through hard surfaces. These blades are the best for cutting rough bushes, weeds and tall grasses. These blades should not be used for cutting wooden materials. The teeth should be sharpened often to ensure perfect results.

There is another class of metal blades which are used for cutting through bushes and wooden materials. These blades have saw-like teeth which are very tough and the best for cutting shrubs, sapling and woody bushes with ease. Such blades should be sharpened effectively to promote high performance.

Blade Factors

When purchasing a weed eater blade, there are a number of factors you should keep in mind. Some of them include:

Durability

Metal blades are more durable than plastic blades. If your trimmer is using plastic blades, avoid trimming hard bushes and tall grasses which can damage the teeth. For metal blades, avoid trimming woody bushes or other hard surfaces as they can damage the teeth.

Plant Friendly

Plastic blades are more preferred for trimming landscapes as compared to metal blades. This is because these blades are softer and more “forgiving,” making it hard for them to damage your plants’ roots. Metal blades are the best for cutting edges, trimming heavy weeds, and lining the fence.

Maintenance

When it comes to maintenance, metal blades can be sharpened regularly to increase efficiency, while plastic blades should be replaced occasionally. Depending on your choice, you can decide to purchase the inexpensive plastic blades or buy a metal blade then sharpen it regularly.

With that in mind, this article will review some of the top weed eater blades available in the market.
