Worx JawSaw Review: If Sharks Ate Trees It Would Look Like This (Video)

The JawSaw is a relatively new offering from Worx that provides the cutting power of a chainsaw with significantly reduced operational hazard via an innovative jaw-like blade housing. The tool is designed for cutting tree limbs, removing storm debris, and pruning in tough situations. The folks at Worx sent us a JawSaw and separate extension pole to try out and review.

Fortunately, we had plenty of trees with dead limbs, enabling a thorough test of this tool.

When the JawSaw arrived, the box was about as tall as me (6 feet). I unpacked everything and was pleasantly surprised that no assembly is required. Score 1 for Worx. Prepping the JawSaw required only two steps: adding chain oil to the tools small reservoir (oil included), and checking the tension of the chain to ensure proper tightness. After that, the JawSaw connects to a standard household outlet and is ready to go.

The tool features a D-Handle with a safety lock on both sides.

The optional extension pole can be attached to the JawSaw for extended reach, but as I note in the performance section below, the tool feels unwieldy with this attachment.

How the JawSaw 

Concealed inside the jaw is a chainsaw that pivots across the mouth of the saw during cutting. When beginning a cut, the blade is fully concealed in the upper part of the housing. This picture shows the blade halfway across the mouth of the tool.

To operate, you put the jaw around a limb, press the red safety lock button, pull the trigger to start the chainsaw, and push the orange handle to slice through. I like that for easier operation, Worx put two safety buttons on the tool, one on either side of the D handle. I also like that the jaw acts to protect the chain from dulling when cutting on the ground. With an electric motor, theres no gas tank to refill or fumes while operating, which are also pluses.

Cutting Power: The JawSaw powered through everything I cut. It had no problem with small to medium tree branches and bushes (4 or smaller). Cutting was very quick and easy. If a storm ever comes through and knocks down a tree, Id be happy to have the JawSaw on hand. Its also easy to know what the JawSaw cut, since larger limbs wont fit inside the jaw housing.

Reliability: After cutting several branches with the JawSaw, the chain came off. I checked the chain tension before starting, so Im confident that wasnt the cause of the problem. I spent about 10 minutes getting everything back in order before I could continue wreaking havoc on my yard. This was a significant drag on the tool, but it only happened once. (As we use this tool further, well update this reliability section with additional results). I experienced no problems with the motor or other parts.

Heres a shot just after the chain came off. Its clearly twisted up inside of the jaw.

After 10 minutes, I was able to get the chain back in place. The nut on the left adjusts tension.

And heres a look at the bush that doesnt exist anymore after the tool was fixed. Id guess it was about 3 in diameter. The JawSaw made quick work of the bush.

Extension Pole: I wasnt impressed with the extension at all. After you snap the JawSaw in place, youve got all this weight on the end of a six foot pole. That makes it really difficult to raise the JawSaw above your head, which is the entire point of an extension. I wish Worx had found a better solution, because I think a long reach is important for a good tree trimmer. Nevertheless, I use the extension pole in the video below.

Heres the short video promised in the title of the article.

Despite the problems with the chain, I enjoyed the efficient cutting action of the tool. The JawSaw powered through every limb I put it up against. The ugly bush in my backyard? Decapitated. The tree with dead branches? Pruned.

The extension pole allows the user to reach limbs as tall as 12 high, but I dont recommend it. The JawSaw is  unwieldy when its attached to the extension. It makes this otherwise safe chainsaw seem unsafe. Fortunately, the extension pole is sold separately.

For $119, the JawSaw is a bit pricey. Wed like to see the price down around $70. However, if youve got a significant number of 3 or 4 tree branches that need to come down, it may be worth it even at the current retail price. We recommend foregoing the $40 extension pole unless you really need it for a job. Use caution if you decide to purchase it.
