    I thought this was a well written break-down of different shapes: www.saraheberle.com/understanding-the-various-shapes-of-trimmer-line/
    It’s interesting that so many different companies have their own proprietary shape etc, but I can’t find any scientific research to back any of it up. Fascinating!

      Robert subscribed then hit the bell. Be more like Robert. In all seriousness I was impressed by how quickly he came up with a well thought out, nuanced hypothesis without even a moment’s notice. Huge thanks to Robert. Also, a huge thanks to everyone who supports Smarter Every Day on Patreon at www.patreon.com/smartereveryday Thank you! Destin

        @Yan May strimmer comes from combining the words string an trimmer together. So you're partly right.

      2. Draztraz

        Weed eater weed wackier potato pototo

      3. Joseph the Inflatable guy

        I often use Echo crossfire trimmer line but I should try out Echo black diamond

      4. Metern

        I would go for the triangle string. Redusing the noise is more important than how the cut is.

      5. Bradley May

        After seeing the 'slo mo' I must say the Aussie slang is bang on the money. We call it the: WHIPPER SNIPPER 🇦🇺

    2. Kendall Winters

      I wonder if Robert has seen your other videos? It's funny that he meets you at YOUR beckoning in your garage while you in mad scientists mode. LOL He is smart about tech and science but maybe just loves hard work so no time to watch. (omg parish the thought!) Wait till he see your other videos. He might come back and ask you to sign his WEED EATER!

    3. Kendall Winters

      I like Robert. Do a video on how to go viral on the internet using Robert! Show us how it's done son! I'm from Texas and we used to call our each other Son instead of boy, man, bro... Anyway... I say weed eater too and string trimmer is the worst thing to call it but I do love strimmer and would say down there!

    4. Jyncarecat

      I call it a weed whacker

    5. pieter

      Bosmaaier

    6. Benjamin Holcomb

      Robert: I wouldn't say expert Also Robert *is clearly an expert* This is the less often seen end of the Dunning-Krueger effect.

    7. Colin Burke

      how does the cord compare to the plastic blades?

    8. Keoki Cosare

      You forgot the air foil shape

    9. Keoki Cosare

      Living inside everybody didn't know cause it a weed wacker and weed eater is a brand of herbicide

    10. tamer ursavas

      HAHAHAHAHA SO FUNNY

    11. Dennis Dickson

      The world needs more Robert

    12. Reinis Sproģis

      My dad once tried metal wire. It still broke apart and the lawn ended up being filled with small needles

    13. Jay Jean

      NY here and I call it a weed wacker

    14. Ananth Swaminathan

      Weed eater? Great video name, yep totally not thinking of anything else

    15. Scrubexpress

      I'm from MA and have literally never heard it called anything other than a Weed Wacker. I've heard "trimmer" sometimes, but I think that's usually for a variant that cuts vertically?

    16. Ryan Linden

      I think the star line cuts cleanest; however, that might not be the case with different grasses or even thick brush. I guess it really depends on type of grass.

    17. D Gray

      Firstly, I found my way here, after buying today, my first ever, electric weed eradicator ! (There's one I bet you never heard ) And after studying to some degree, felt like I was splitting hairs when it comes to cutting weeds/grass. And seems that unless the tool is just very poorly designed, they all do about the same ! However, there are some huge differences in pricing. As to this video, I think the biggest surprise for me, was the inaccuracies of the initial strikes ! I would think the leading edge of the grass would be struck first, but the video clearly showed many stikes at the center of the blade of grass happening first ? What phenomenon caused the leading edge to be missed ? Has anyone ever experimented with segmented line that actually incorporates a flat line between other shapes ? As it might serve to make the line lay more flat, allowing for a cleaner cut ! Also I wonder about prescribed rpm from each manufacturer, as if their line is built to be used at a specific rpm for optimum performance ? Having never gave it any thought, I too was surprised by how the grass is torn apart, as opposed to a clean cut, much like the difference between having a sharp lawn mower blade, or a dull blunt one ! What else will we pick apart to the finite ? Or should we surrender to the realization that no one will make a product that you only buy once ! I think from my own experience, and I think mentioned here, is controlling the rpm, especially when working near things like a chain link fence ! Seldom do you need to run at maximum rpm. IMHO !

    18. Captain Duckie

      It’s whipper snipper or weed whacker. Nothing else. Thank you.

    19. Jayden Reece-Harrison

      "Australia calls it strimmer" Nah, the chart was correct, we call it nothing but a "whippa snippa" (sic)

    20. Yod Yodhi

      I call it a wipper snipper

    21. Jitesh Ramakrishnan

      Shoutout to Robert the weed eater dude.

    22. Name Last

      The saw blade adapted too it last way longer than. String. Because string always breaks. .

    23. PauL1e

      Its trimer in winland

    24. Вячеслав Иванов

      The problem is you dont have accurate shape of cutting edge after a few seconds. so yeah, only weight matters

    25. Jim Powell

      What about the attachments? Which of those is better?

    26. fekard

      Are these strings biodegradable or made from plastic? In which case we make microplastics.

    27. B whin

      A wiper snipper

      1. B whin

        A whipper snipper

    28. Gary Chandler

      The grey line with the spiral groove is, I believe, Husquevarna that I used a lot, beecause it lasts longer, especially on rocks, curbs, fencing. But - it doesn't cut sharply, so dont expect less than ragged tops. Now using some star shaped thinner line (.85) given to me, and it cuts really well for grass, but not so good in the bushes & heavy weeds.

    29. Wretched Slippage

      Project Farm just came

    30. Wretched Slippage

      The star has more cutting edges making it more likely to hit the grass on the cut than on the dull.

    31. phrawg boi

      I like robert. He's chill

    32. Blank

      I call it a weed eater but I just realized I have memories of it being called a weed whacker when I lived in PA for a few years, lol.

    33. Solsol

      10:04 spot the tiny TINY bug on the second grass!

    34. mcburcke

      The Stihl company studied this years ago when they were considering making shaped line (other than round cross-section) and they found that after a few minutes of normal trimming use , all of the various shapes actually wore down to a tapering point and were cutting the same way. Stihl engineers couldn't find any measurable improvement from any shaped line over the standard round line. The only thing they've done is add the spiral groove to cut down on line noise.

    35. Larry Seibold

      really cool. I wish you 1. asked robert why he used what he did; and 2. tested the top contenders in real grass and bush conditions outside and viewed the results (clean, speed, durability/$).

    36. Jimbobjoe 46

      Its called a strimmer

    37. Benevolent Protector

      ..and that's why it's $18 a roll

    38. Alexander Margas

      i live in Florida and call it either a weed whacker or a trimmer

    39. TheGhostFaceKing

      Omg! I get the same kick outta hearing and watching people do the same thing and subscribe. Lol. I Love helping and seeing Humanity learn new things! Its awesome. Subscribed as well 😆

    40. OobleGoo

      Whipper snipper

    41. PhlippyG

      I love robert

    42. Peter Denison

      As cool as this video is, I value durability over cut quality in my weed whacker/eater.

    43. Papi4l2

      My fav. So far has been the Rotary Vortex line. Echo black diamond seems like a copy...havent used it myself

    44. MacGamer Media

      I say weed whacker. It’s better because alliteration rolls off the tongue.

    45. Grace Nicole

      I´ve lived in Indiana and around the Chicago area my whole life and have only ever heard people call it a weed wacker so when I saw the google stats I just had to go ask all my friends what they call it to make sure I wasn´t crazy

      1. Grace Nicole

        So far four of them have responded and they have all said weed wacker so we're good

    46. Davo da great

      I grew up saying weed eater

    47. Super Stuff

      I call it "weed eater" but if you listen to it, it goes like this against the grass: WACK WAK WAC WACK WAK....

    48. h3ssto

      Weed Eater Man needs his own channel...

    49. Nk

      puzzle by different products at the mall? Ask Project farm "PF"

    50. RNdom

      Im in kansas and everyone i know calls it weed whacker Soo.. idk

    51. jamcdonald120

      1:15 "Thats how I do it, Thats how Dad did it, and Thats How America does it. And its worked out so far.

    52. Ant Man

      I really don’t think the shape is making much of a difference. The fact is you wouldn’t really be able to tell which shape was used by glancing at a freshly cut lawn so why even care about it? The only real concern you should have is for durability.

    53. Mark Grassl

      ...In german we call that thing "Motorsense" or "motor sythe" if you translate it literally.

    54. ManilaChillRide

      Grass cutter

    55. Corey Flatt

      Table trippy snipped

    56. RCoady

      You also used virgin line not used line. The line may sharpen with use

    57. Oliver Rosenkrantz

      Very intereSTRING

    58. Birch Weber

      I don't think it was a good choice to weigh down the grass with the clamp. The weed eater wire is not designed to cut taught grass.

    59. Fernando Flores

      Weed Wakah! 😅

    60. Péter Visi

      Robert is an absolute legend! I just found this video now, have no clue how am I missed it. Probably I didn't hit the bell icon like Robert did. I did not know until now, but this video is just what I needed now.

    61. OMG OMG

      Can we have weed smoker machine in the future xD

    62. viewer1431

      I say weed wacker, haha. Do you guys know what Gooseynight is ?

    63. Nathan R.

      Fun fact: In Malaysia, people call it a grass cutter

    64. Jill Booth

      75% explaining what's happening 5% science 20% im a adult who knows big words

    65. Greenicegod

      I worked as a grounds keeper at a university in the mountain west, and we called them "Weed Whips"

    66. Daniel Hale

      IMO this is too philosophical for my taste. You find out by actually going out into the yard and weed eating, then assessing the results. Trying to extrapolate on the value of each line this way is just... wildly unhelpful. Why speculate based on experiments that are detached from the real world when you can go empirically find out? Why not follow up by taking the weedeater outside and going to town on some grass, shrubs, etc to see what serves your purposes the best in actual practice? Why not check to see how the grass regrows after? It may be that clobbering the grass blades instead of clean cutting them isn't a big deal.

    67. Osiel

      Here in Texas my Mexican family, and many others that we know, call it a "wirira" or "wira" which comes from trying to pronounce Weed Eater.

    68. محمد الزعبي

      I call it weed yeeter

    69. ar a

      In Germany we call it MOTORSENSE

    70. Mike Hill

      Will a cleaner cut change how quickly the grass will grow back next time?

    71. Tecueme

      podadora

    72. Scott Adams G [Scotianbank]

      A "weed eater" is as much of a weed eater as the Cookie Monster is a cookie eater... They only chew them up and spill everything out

    73. Scott Adams G [Scotianbank]

      As someone not from the US, how come I've always known about it as a weed wacker? My family's from Texas, and they say weed wacker, and I swear that I've always heard "weed wacker" when used in a movie or show... I had never ever heard the term "weed eater" until Destin's previous video about them. Weird...

    74. Craig Morley

      In Sydney, Australia we say whipper snipper....🐨🦘....

    75. Fanny Magnet

      Weed wanker??

      strimmer and yes i am UK haha

    83. MrClaypogue

      Star is like using a high tooth blade it makes smaller slices of the grass each high point breaks off /cuts the grass at that point but it would also be rotating ever so slightly back and forth which would act like an ultrasonic saw essentially.

    84. Antonio Rios

      its a weed whacker it whacks weeds

    85. Douglas Folk

      You do know that Weed Eater is a registered trademark / brand. This is like people in the south calling everything "Coke" when they want a Pepsi or other soda/pop/tonic type drink. :)

    86. Норден Конрад

      How much plastic ends up in a square meter of your garden?

    87. RichardofOz

      Did you allow for different materials used in making the lines? And did you contact manufacturers for their test results and reasons for using different profiles? They've probably done a lot more testing than you ever could. And if you're cutting brush, you probably don't want to use line at all. Use the steel fittings that really handle the heavy stuff.

    88. Alan Fletcher

      From a golf course super which I am not. The cleaner the cut the faster the grass heals which makes it grow faster. That's why mower blades are not razor sharp. I like to mow less so ripping the grass works for me.

    89. Molly Gundies

      What do the lawn care experts say about trimmer string?

    90. Horizon

    91. Daniel DiBono

      Ok so it looks like everyone agrees weed "whipper snipper" and strimmer are not at all names.

    92. Wolarski

      how about using a lawn mower? lol blades > string

    93. Sabi1234567890Asdf

      How many times do I have to watch this to get Robert a case of beer I'm about 50 times in since the release. Ps if you want more consistent data I would think paper would be a good sub for grass.

    94. Triste 421

      Doesn't it depend on the type of grass too?

    95. Anthony Barrett

      Mate, Destin. Nobody says strimmer here. Always whipper snipper. Always!

    96. Svndwich

      Weed wacker

      1. Svndwich

        It doesn’t eat the weeds it just whacks them really hard

    97. Jasper

      whipper snipper ftw

    98. WafflesEatDogs

      its a weed wacker

    99. mozkito life

      You should've heated up the sharp-sharp square to straighten it up. It's curved because you used a short strand of it instead of off the roll. I'd like to see a dB reading of each strand next time.

    100. Brandon Knudsvig SHARE Media

      So relieving knowing someone else overthinks these decisions that should be easy. Only thing is I just waste 20 minutes trying to learn about hem them, never really being sure if I got the right one!!!
