    Very sharp and cuts great
    This blade comes extremely sharp and ready to cut. It is easy to install you just have to have a blade installation kit to hold it on. Instructions are not completely clear on which way to put the blade, but if you know which way the head turns its easy install

    Good tool for a variety of issues
    Bought for my FS110 to help clear about an acre of mixed undergrowth on my new property. Since it's winter, I haven't had any long sessions with it yet, but what I have used, I'm pleased. Will buzz through small saplings and briars quickly. Can get very close to the ground to minimize obstructions when mowing the newly-cleared areas. Have not sharpened it yet, but the ability to sharpen the blade at home was one of the determining factors in choosing this blade. I suspect that a little file work ... read more will make it sharper than factory and a faster tool.

    Very good choice for brush and small trees.
    I use this type of Chisel Tooth saw blade on my brushcutter and have found it to work quite well on scrub brush and small trees up to three inches. Although it needs to be professionally sharpened, it stays sharp for a long time if you don't get it into the dirt. I purchased different sizes for the type of tree or brush I choose to cut and they all perform exceptionally well. One piece of advise, purchase more than one and you won't have any downtime. Great product for the price!

    Great clearing saw blade
    I purchased this scratcher tooth blade earlier this year for cutting down smaller trees with my FS90. This blade has no problem's clearing trees up to an inch and a half in diameter. Trees larger than that you need to spend a little more time with but still there aren't any issues dropping any tree that's within reason.

    Great for small trees
    This saw blade has been a lifesaver for cutting down small Honey Sucke trees up to 1" in diameter. This species of trees is taking over Missouri forests. Not so great for Blackberry brush, but Stihe has other blodes that will work on any thorn bushes.

    Clears Heavy Brush & Saplings With Ease
    We have a bad invasive European Buckthorn problem here. Until recently I have been trying to clear them with a chainsaw and loppers. I finally picked up an FS 110 and this Scratcher blade. This combination helped me clear the buckthorn at 3 times the speed I was doing it before. I wish I didn't wait so long.

    Perfect for Boulder Walls and Foundations
    I love this product. Gets all the weeds growing at the bottom of my 100 foot boulder retaining wall. The string trimmer wouldn't survive and the boomerang blade throws too many sparks. The PolyCut blades get in every corner and wear down nice and evenly. With any other tool this job would take much longer. Be aware that after such heavy use you will need replacement blades every time. Along my foundation wall they last much longer.

    Savage
    I went into the store to get a metal grass blade and was begrudgingly talked into this cutting head. I really had my doubts that it could handle my garden. I had massive weeds (>6' tall) and raspberry bushes. You couldn't walk through the garden. This mowing head went right through everything. It absolutely decimated everything in its path. This thing is a monster in all the best ways. Also, it is incredibly easy to swap between this cutting head and the string trimmer head that came on my FS-56.

    Excellent for brush and grass
    My parents had one of these trimmer heads on a sthil brush cutter when i was growing up. I used it to mow fence lines, drive way banks, and trim around the house and barns. When i got older and bought my house i also bought a fs55r and when i picked it up from the dealer it had a string head on it. I dislike string heads so much i gave it to the dealer and had them install the poly cut head. I will never use another style of head on my trimmer. I get two or three trimming rounds at my 6 acre ... read more property from one set of blades.

    I LOVE THIS PRODUCT!
    I love my Stihl FS55 string trimmer but could never complete my entire trimming job without stopping to remove the top of the bump-type head to re-set the string because it would break flush with the edge of the head. With the new Fixcut head I can easily replace the string in seconds without removing the head. I LOVE THIS PRODUCT!! If you buy one of these Fixcut heads, you will not be disappointed. I should have bought this sooner. This head should come standard on all their models.

    More efficient than an auto feed head.
    SURPRISED: This is my third season using this head. I had all but given up on using string trimmers until I found this head. Most people probably won't agree on my efficiency comment. But, it beats untangling auto feed spools any day. MAINTAIN: I have found that the head must be taken apart and cleaned on a regular basis. I soap and water to clean & silicone spray sparingly to lube the pins. This is a must if it is being used around sandy soils or in dry conditions. LINE FAILS: As to the pull ... read more out problem I find that the line striking rocks or rough cement to be the biggest cause. I find that having a pocket full of inserts and a pair of pliers is much simpler than fooling with auto feeds.

    Great and simple
    Great product. However I lace it with 2 strings so it has 4 ends sticking out. Its raw, I want to try lacing it with one string and see how that works.

    Excellent compared to the bump spool line trimmer.
    I bought the Stihl KM 130 motor head and also attachment for the brush cutter. I have another line trimmer attachment with the bump spool trimmer and always had problems with the line feed. While I'm giving this line trimmer to my son, I bought this trimmer head to change out with the brush cutter attachment. What a difference and joy it is to use. It is not that expensive either and well worth the change compared to the hassle of having to deal with a bump spool. Lines are easy to remove and ... read more change out when needed. You can also get easy replacement lines or buy a spool and measure and cut your own trimmer lines.

    Love it
    The DuroCut Line Head was very reasonably priced and works wonderfully. The line is very easy to replace on the head and I'm very happy I purchased the head when I purchased my trimmer.

    Much better than "bump & feed"
    I totally agree with Gary86. The DuroCut is MUCH easier to use than the bump-&-feed line head that came stock with my Stihl FS-56 trimmer. Although you can't feed line on the run with the DuroCut, most of the time my bump-&-feed head wouldn't either. I would spend more time unsnarling the spools and re-threading the the head than trimming. I tried several brands of line (including Stihl) in effort to find some dependability and ease of use in the original head. The DuroCut uses much heavier, ... read more serrated pre-cut line segments that are tougher and longer lasting than the original line. When you do have to stop and reload line, its quick and easy. Just pull the remaining line segment out through the center, push the new line in from the outside, and GO!

    The BEST overall cutting attachment for Brushcutters/Clearing Saws!
    I have logged over 4,000 hours of cutting with the 350mm X 3-tooth Brush Knife. I've whacked green wood upwards of 3" in diameter. The blade clears itself well from tangling of wire-like weeds. It is easy to sharpen by hand or grinder. Make sure you keep it balanced. The two-sided feature means you can flip it over in the field & keep on cutting. This blade is not on the recommended list for the FS 460 series Clearing Saw, but I can tell you that it works just fine on that unit which has ... read more adequate power to swing it. This blade will clear all kinds of grasses, weeds, brush, and sapling trees.

    Best Metal Blade Available
    I purchased my brush knife a year or so back and since then it has seen regular use on both my FS55RC and FS90. This is by far my most favorite metal blade out of the ones I own. I have cleaned up areas with briars, small saplings, random undergrowth and brush that would take a man several hours to clear by hand. With this blade however I'm able to clear through the thickest of brush and the end result is a nice clear area.

    Blackberry Killer!
    I have a KM-94R and the FS-KM brush cutting attachment. I had a field of blackberries to kill and my local dealer suggested this blade. It's a little pricy but after using it I found it to be a great value as it sliced through 1.5" blackberry vines without even a hint of slowing down the engine. Even at half throttle! I hit a few metal objects that were hidden in the blackberry jungle and to my surprise there was very little damage to the blade. I was able to file out the dings and it's good as ... read more new. I could see how it might not be mounted on center and cause vibration as there is no real key except for a small lip against the head. I'm glad I bought this blade as it made my job quick and easy.
