    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

    I think the star works the way it does because there is always an inefficiency that is consistent instead of a more turbulent result coming from less cutting surfaces on the square or triangle where sometimes you hit it at the right angle and it works very well or it pretty much explodes the grass.

    My own opinion, the Star shape cuts cleaner because each contact point regardless of its rotation is a uniform length when it touches with its flat edges. Occasionally it’ll cut using the vertices, and considering there are more of them, it’s also a higher chance you’ll make contact with one of those corners. You’re trading off a sharper edge for more edges, and consistency?
    Also considering you’ve sacrificed how tight the edges can be and thickened the wire to create more contact points, it’ll have a harder time cutting thick grass more consistency due to the thickness

    Question.
    Why would you use Weed eater around the house where you have small soft grass.... isn´t lawnmower better? (doesn´t make such a mess, quietter etc...)
    Weed eater is for hard terrain with variety of grass (like thistle for example). It is these hard grasses that weed eater lines have problem with. I would like to see experiment on these.
    Interesting video nentheless.

    Very nice video. I have some suggestions, I think you'd have tested (if available) different thickness of the same shapes, and in different grasses. I just use round lines but with two thickness, the thinner is better for regular grass, is faster and the weed eater doesn't shake as much, but it's terrible at bushes or thicker grasses where the thicker line cut just fine.

    inconclusive. you removed grass from it's natural location which is far from actual usage and performance.
    practical tests could be how durable is it, noise level, cost per foot and such. then compare to hard line replacement heads, or even just compare those ( single strand wire, multi, cable, and blade)

  • Slider68
    Slider68 Giorno fa

    My main question is what cord produces a cut that is the healthiest for the grass? Intuitively a sharp, clean cut is best - but is it really??
    For me, since most of my whipper snipping is of heavy, thick weeds, what I'd really like to know is what is the best for cutting heavy weeds. I'm seriously considering replacing the cord with a 12" skill saw blade. I borrowed a whipper snipper with a 12" blade years ago and it was fantastic at chopping through the heaviest weeds and through small (up to ~¾" dia) trees. Is there anything better than a 12" skill saw blade for heavy weeds?

  • MyTech
    MyTech Giorno fa

    The weight-tension on the grass blade seems like a possible source of error.
    To be apples to apples, I found a .080 square section weight is about the same as a .095 round section. Also tendency to get split ends make a big difference after just a few minutes of use, and the titanium brand I have found to give very good results.(I have not compared value of said brand)

    Sharp- Sharp Square is better for mulching the weeds and Pulverizing the remains, So they don't grow back as quick. Sharp cuts are what you want for a green lawn, not weeds you don't want.
    .... The Grey Husky line is my personal favorite, because of its high speed, and Just by listening to the sound I can tell if I need to feed out more line. Also the grey shrapnel blends into ground, so I don't get distracted by O.C.D. picking up neon filaments when I'm trying to enjoy the yard.
