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.

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

I wish your mantra was "Let's go get smarter today" (keeping the channel as SmarterEveryDay obviously, in that it's the collection of getting smarter today in each episode). Feels like it would mesh better together. Saying "Let's go get smarter everyday" feels like it has grammatical and tensional issues. Anyway, just nit-picking. Love the content :D :D

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!

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?

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.

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 !

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.

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.

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.

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.

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.
