I thought this was a well written break-down of different shapes: https://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
Thank you!

Robert: "It seems likely that this line, being lighter and possessing a smaller diameter, would travel at a greater velocity, perhaps facilitating a cleaner cut."

Destin: "ShARp shARP sQuaRE"

No one in Australia called it a strimmer. I’m sure everyone will agree when I say it’s called a whippa snippa.

I love how Destin's accent gets much thicker when he starts talking with someone from around the block.

Fun Note: Truck drivers put a single twist on the belts securing loads to flat beds to prevent the belts from vibrating. If you follow a truck with belts not twisted you will notice the belts vibrating but the belts with a twist will not do anything. Your mention of the triangle twist at made me think of this.

I've only ever heard people call that device a "weed whacker". Those analytics results blew my mind lol

by Bubble Boy 1 week ago

Robert's line was also from a larger spool compared to the others. Maybe his line deformed due to how it was wrapped, resulting in a wonky rotation?

by ixovera 1 week ago

Aussie here, Can confirm I've only heard other Australians refer to them as a Whipper Snipper.

"he suggested that we weigh each line in a certain length and calculate it's linear density"
He did what?
Clearly got Audible in his ears for those 10hrs of weed eating he does a day! Cause I sure didn't think of that!

The fact that Robert is not objecting and play along is quite admirable

Random WeedEater dude: "Ya'll need to weigh the line by length and calculate the linear density."

by Edward's Sisters'Hands 6 days ago

Some key points left out are that the size and weight of the line used has to be matched to the speed and power of the weedeater (Northern California person, and that's the most common name around here lol).
As you showed previously, if you make the line too long it slows the motor down, and the same is true if you put a larger diameter or heavier line on than the motor can pull.
So Robert's unit is most likely much more powerful than yours, and so would have no problem straightening that line out, and possibly also spins at a faster rpm.

The other big reason for using different shape and style lines is line life.
A round line will cut grass just about as well as an equivalent other shaped line, but it wears off on rocks and fences and such much faster. The shapes seem to give it a buffer or wear guard to protect the core longer against debris wear.
It also can make a difference when getting into star thistle, blackberry vines, etc, where a round line just slides off, but a textured line digs in more, and doesn't wear as fast.
I am basing this off experience and logic, so I could be wrong, but it's worth testing lol
