[@vigilantcosmicpenguin8721]

Destin's greatest achievement was introducing us to Weedeater Guy.

[@BigBear--]

One main problem I see is the tension put on the blade of grass. In the “field” the blade is sorta just hanging there freely, I think it messed with the dynamics of the cut by putting the blade of grass under tension…and we’d see very different behavior if only one end was held in place and the other allowed to dangle freely.

[@BlueChickenFarm]

This!!! I would have liked the clip mounted below holding a piece of grass upright

[@BigBear--]

@@BlueChickenFarm btw, I've settled on that either the Husqvarna Titanium, or the Husqvarna XP+ Line as the best trimmer line. That stuff is strong, flexible, and cuts clean. Most pros that care use either the stuff I listed, or the Echo Black Diamond.

[@xzantronos]

@@BigBear-- echo crossfire line, husky titanium line imo are probably the 2 most durable weed eater lines on the market. I have never been much focused on shape of the line but durability of it and tracking capability unlike that sharp, sharp square that was all over the place.

[@ADBBuild]

THIS! Easy way to think about it is cutting a piece of rope with a knife. Unless you have an incredibly sharp knife, you aren't going to cut through a piece of rope hanging in mid air as it will just be pushed away. It has to be held under tension for the knife to cut through. Inversely, by hold the grass blade tight, you are making it easier to cut and distorting how it cuts.

[@BigBear--]

@@ADBBuild Over a year later my bottom line is when it comes to trimmer line - get yourself either the Husqvarna Titanium, or XP+, or get the Echo Black Diamond. I personally prefer the Husky line. That stuff is super tough, tracks straight, and cuts clean. Also a small recommendation is soak the line for about 24hrs in some water...cause a lot of the time you never know how old it is, or how it was stored or transported. Soaking it in water sorta re-hydrates it, and prevents it from getting brittle. You can also do that to bring it back to life, if it goes stiff on you from dry storage every season.

[@benjaminholcomb9478]

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

[@benjaminholcomb9478]

I should say middle. No one really gets to the far end lol

[@ryurc3033]

You have to know something to realize you know nothing.

[@Aim54Delta]

Dunning-Krueger is poorly understood. The study, and subsequent efforts, have demonstrated that people tend to presume they are average in performance regardless of how their performance ranks in absolute terms. If I were to take 100 people sampled at random and have them run, say, 3 miles, we would see them string out, with a few running far ahead and a few practically walking from the beginning. Most will be relatively close to each other or even herd together. Run them all individually to see how they perform, and you will break up the herding but not the statistical clustering of scores. Most people see themselves as "part of the pack" - be they at the rear of the pack or the front. Only when you have them perform as independent individuals can you properly assess their individual capabilities - the fast will not slow down to lead the pack, for example, and the slow will pick up their pace to not lag behind. Our perception of our individual capabilities is seen through this lens. People naturally perceive their performance as existing relative to this pack cluster with those tat the front not understanding how easy/naturally they dominate and those at the back not understanding how hard they have to try to keep up relative to others. Thus, people at the back think they are closer to the middle than they truly are while people at the front do not understand their own superiority.

Other styles similar to the traingle line or the round line seem to wear out after just 1 day of trimming.

[@RonJordanpopcornRon]

So glad to know that years ago when the new lines came to life, my take is the same. Star and gater line is the best over all. The 4 edge (squared) like Robert mentioned how it will do for roughs and can cut through tough grasses is not a go to for manicured lawns. It wants to climb down into the grass and get away from you before you know it and then you have a bad spot that is there for the customer to see. All in All a round weed eater line will give you a smooth cut like butter in grasses such as Bermuda & Zoysia grass. In doing so it kind of rolls over the top of the grass while you are cutting without digging lower than what you want to go. And in working throughout the years you learn to slow down your weed eater throttle with your smaller line along your fence so you don't go through it in the first 20 feet.

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.

[@shanereilly9309]

I had a lawn crew for a couple of years and I found that the thinner the line the cleaner the cut. Now the thin stuff works great for a homeowner but I found square gator line with a wire in it left a good product and lasted pretty well doing production. Then there was this braided line it left a satisfactory product and lasted remarkably long. Both were commercial grade. Sorry I can’t remember what the braided line was called it has been more than ten years since I could do the work. I really liked the gator line the best. Great video.

I came to a decision about trimmer line, even before watching this video! My take-away from all this testing is, if you have to get down to the macro-lens level to see a difference in how your line cuts grass, then save yourself some bucks and buy whatever is cheapest, in the diameter(s) you need. Guaranteed, NO ONE is going to walk by your yard and say "Oh look, he used the wrong shape of trimmer line."

Definitely rigorous scientific research! You can't control all the variables without spending way too much time and money, but the experiment with small variables like the speed of the trimmer and the thickness of the grass aproximates the actual working conditions, so the accuracy of the test reflects real world results. I appreciate the time and effort doing this test. I have personally use the star shaped line as I was swayed by advertising some years back, also because it creates a cleaner cut the grass will be healthier in the long term.

[@kotgc7987]

Thanks, I have always wondered about which whipper snipper line to use. I use electric garden tools for my corner house and the 2 neighbours' front gardens.

I love the slow motion and super crisp, close up camera work! Great job guys!!!

[@Angel.76239]

Overall great video! Ive been working in the landscape business over 5 years. Now there really isn’t “the best line”. It all depends on what your doing. There is pros and cons with every string shape. Another thing to consider is the thickness of the line, for every shape and brand there is different thickness sizes. If your edging sidewalks, or weed eating somewhere with a lot of rocks, or metal or debris, then you would want a thick round trimmer line. This shape is especially made for not breaking as easy. If your weed eating thick grass or brush with no rocks in the way then I would use the diamond shape. Which looks like a twisted string. An example is the echo black diamond. Also known as “sharp square shape. This line is meant for thick grass and weeds. It is not meant for edging, nor weed eating around rocks, fences or debris, because this type of line breaks easy. In my business I only use Husqvarna titanium force. Which is a thick round line. I use this because this line does not break easy, it is durable, and can cut through thick brush. This line is not meant for thick brush, but because we have high power commercial trimmers it knocks down weeds like nothing.

[@kyoswkyosw1216]

We have a triangle line up here that the corners are actually stronger than the core, so it splits apart through the middle of the line making each string actually three cutting pieces at the end of the line while trimming instead of one big piece

[@kosherartwerxllc]

The clean cut also being healthier for the grass.

It's about maximizing shear force at the contact point. The star shape does it the best. But with thicker diameter material, the square has a better chance of avoiding the flat contact scenario.

But then wouldn't the round shape be better since a circular shape has an infinite number of edges?

Because of a future Honda recall, my HRX217 has been in the shop for months, and I had to cut my entire lawn with my weed eater. I noticed that the cheaper more economical lines damaged the ends/tips of my grass so badly, an hour after cutting, my yard looked brown and dead. I tried different lines, to try to get a cleaner and healthier cut - So my yard would look green and healthy an hour after cutting. I found that the twisted .105 You gave me the best results and the greenest and healthiest looking yard!
