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!

  • 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.

  • LOL you say 'most people call it a weed eater' then justify it with a state by state map of the USA.... then put out a country map with only the countries that call it that shown plus UK and Australia as token outliers. Do a county by county map of the UK and the results would be totally different. Most people who live in America and south Asia may call it that, but most people who live on Earth probably have never heard of the term. Try asking for a 'weed eater' in Russia, China, anywhere in Africa or Europe, or the other countries you have conveniently ignored.... It also seems like the non North American countries that have heard of the term happen to be the ones in the are most electronic waste is sent to, so they more than likely picked up the phrase that way.
