Why do they call it "cordless" when it uses string

This question is from 40-Volt Electric Cordless Straight Shaft String Trimmer
Asked by
Fresno, CA

March 4, 2016
I have had horrible luck with string trimmers in the past. Hoping to find something that uses blades instead of that annoying string. Why are these products called "cordless" when some kind of cord is used to knock down weeds? The category "cordess" raised my hopes, which are now dashed. Every product description I opened uses string, which is a variant of "cord."

Answer: 
If, your name IS Alice, I think you are a troll. If you are NOT a troll, you are clearly ignorant. If you have read the tool description, you know the answer.
I'm really surprised that no one else thinks you are "pulling their leg" (aka trolling) with this question.
Technically, a string trimmer can also be a pair of scissors or a knife.:)

Answer: 
Some trimmers, such as this one, has a replaceable head, meaning you can take off the head that uses string, and replace it with a head that uses plastic or metal blades. They call those brush cutter heads. That is what I am going to do.

Cord in this case refers to electrical cord that powers the trimmer, not the plastic string that trims or cuts grass/weed. I'd be eager to get a stringless trimmer myself. Even better if it uses air rather than blades.

Now this prior trimmer held up for well over a decade with comparatively moderate weekly use. But eventually, it's battery gave up the ghost, and I decided to treat myself to a new trimmer. So I would assume that this lithium-ion styled battery won't hold up forever. I just can't predict how long it might last, though. I can tell you that I ran through a lot of lithium batteries during more than 20 years of schlepping around a series of business PCs. Read Less

Due to the higher capacity battery this model will probably be heavier than older models your Dad is used to using. I found my arm was getting a tired pretty quick compared to the older model B&D I had intended to replace this unit with.
I found the battery run time far shorter than stated on the box. I was completely out of power in less 30 minutes.

It's vey light compared to a gas trimmer. With the battery in place it's also well balanced. Not knowing your fathers physical abilities I would recommend visiting a Home Depot and letting him get a feel for it. As for the battery, it has never let me down. I use mine weekly for basic clean up after mowing. A half hour of use on medium speed and it has never pooped out. I was very skeptical about buying this. But after years of battling the mix gas trimmers not starting, running erratic, throwing projectiles at 100mph at me and everything around me, I gave this a try. 2 years of loyal service. Couldn't be happier. Keep in mind this is a maintenance trimmer. You can't go mow down a field of 4ft. weeds. But to keep a maintained yard maintained, this is must have. Read Less

I think it is lightweight, but I used to use a 4 cycle gas trimmer. It is hard to know if it will be good for your dad without knowing whst "lightweight" means to him. I have a small townhouse property of 6000 SF so the battery life is fine 4 me. It has different power settings so you can dial it down to lower power to & the battery will last longer if you are just trimming grass.

Rated 4.6 out of 5 by 943 reviewers.
Rated 5.0 out of 5.0 by Great Value Great value for the price. It's lightweight and very powerful. The only downfall is the battery life. It runs out before I finish the entire yard (even when I use it on the lowest setting). June 30, 2016
Rated 3.0 out of 5.0 by It's just OK. We have a B-D 24-Volt string trimmer with Ni-Cad batteries which my wife really likes. The charger failed (full charge cut-off died) and cooked the batteries. Bought this 40-Volt unit expecting even better performance. Oddly it doesn't seem to have the power of the old piece. Trimming is fair but when used in the edging mode it doesn't do nearly as well. I bought new guts to rebuild the old 24V batteries and a new charger and now the Boss Lady is happy. We'll be returning this 40V trimmer. It would do if you have nothing else but we were disappointed. August 16, 2016
Rated 4.0 out of 5.0 by Good tool for small women Length be adjusted for short arms and short height user. Also you don't have to pull line out by hand after the old tap feed system stopped working. The best part is the ease of battery removal for which a large hand was needed in my old trimmer. The battery in this one slides easily into and out of a slot. No large grip required. Only had this a few weeks. The machine cuts well and has enough power to cut our nasty tough Eastern Washington invasive weeds. No idea about battery life yet but an hour of cutting does not run down the battery. 4 stars for not knowing whether battery will live more rhan a year. August 2, 2016
Rated 5.0 out of 5.0 by The greatest! I live on a hill in the Hill Country on mostly rock. It is impossible to use a lawn mower. My husband is not able to help me now so I had to get something I could easily start. I have about an acre that I keep trimmed...grass and then dried wildflowers. This is the greatest string trimmer. I purchased an extra battery and worth it because I can do most of the property in one morning. Before when I used a gas trimmer I had to stop and reload the string. This trimmer shoots out the line without tapping it...wonderful. Further, because we get drought periods (like now) I don't use a trimmer every week and then had to pour out the old gas and replace it. I've also purchased the B&D 20V chain saw for trimmer....also a great item. Oh by the way, I am 79. August 10, 2016
Rated 4.0 out of 5.0 by Outperforms my old battery string trimmer Very simple to assemble. Easy to operate and I like the ease of extending the length of the shaft. Used it to clear overgrown brush. It worked well and I was able to cover a large area. The battery ran long enough for my arms. This trimmer was a good buy. August 19, 2016
Rated 5.0 out of 5.0 by Best weed trimmer ever had This is the greatest trimmer. It's as simple as pushing a button and starts right up! The battery lasts quite awhile and haven't had any problems with it losing its charge. I can weed the front, back and side yard non-stop and it still has a good charge left. I'm 5'5 and my husband is 6' and we can both use it easily by adjusting the length of the handle. My husband has done a lot of landscaping work and said this trimmer is the easiest he's ever used. He'll never go back to a gas or electric trimmer again. August 2, 2016
Rated 5.0 out of 5.0 by Works as well as some Gas powered trimmers! Just like I had hoped! It is strong, lasts a long time on one charge and makes trimming and edging simple and quick. The speed adjust control makes it much easier to use instead of beating a smaller amount of grass at high speed, it can be slowed down to be much more exact as to what you are cutting. But if you need high power, it packs a punch! High, thick grass gone in no time, to the level you want. And the wider diameter cutting edge makes the job go much faster. I like mine very much! August 9, 2016
Rated 2.0 out of 5.0 by Difficult to use To start, one must simultaneously depress two levers. This is very hard to do if you have smaller hands. I have started it successfully, but continue to have difficulty and sometimes just give up out of frustration. August 22, 2016
