    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 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

    Great Trimmer Addition
    I just recently bought an FS90 and got one of these with it to clear stubs and small trees from the 5 acres with our new home. The blade turns the FS90 into an unstoppable cutting matching. Anything 3" or under is easy to cut and anything .75" or under is cut while swinging with no more resistance than grass. Highly recommended.

    Saw blade cuts like a saw.
    I put this on my FS240. Brush and saplings fall like trimmer line through grass. Small trees go down like they're cut with, well... a saw! Tree size is limited only by blade depth. If this on a 240 won't cut it, get a true saw.

    Cuts Through Anything....just about anyway
    I purchased the Scratcher tooth circular saw blade to go on my Kombi KM90R with the brushcutter attachment. Swapping it out was a breeze and this thing will cut through most all briars and small saplings that I could put it through. I was cutting up to 1 1/2" saplings with it without a problem. I bounced the thing off a few rocks which made me nervous but it did not affect the blade at all.

    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.

    This thing ROCKS!
    I just got the FS130 with bicycle handle and the full harness. First of all the harness is amazing, do weight on your wrists, you basically guide the machine. I bought this blade for blackberry bushes and i can tell you it eats them up. I've been wanting something that keeps me far enough away so i don't get snagged on the bushes and this does it. Very impressed... not cheap but it is worth it!

    Using it with a FS 560 is unbeatable
    I purchased two of these for my FS 560 that came from my Southern States dealer in Lebanon, VA. The team there is great! Anyhow, this blade is unbeatable. It does great on grass, but can tackle nearly anything I can throw at it. We are in rocky limestone terrain, with autumn olives, blackberries, wild roses, etc. It's a mess of over grown pasture field, but this combo cannot be beat. The FS 560 is a beast of a machine, and the other blades, the scratcher, and the circular blade have their ... read more places, but this best all round one.

    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.

    Very durable. I use .155 spiral line.
    I bought this with my FS-56-RC-E trimmer because it was the only head that was big enough to use my .155 spiral line in. I store my line in water until I use it. The ONLY time I have to replace my line is when I use my trimmer as an edger by cement, or when I get too close to the chain link fence. I use 2 lines in the head so that I have 4 pieces cutting. I love this head. I've used it for 2 seasons with absolutely NO problems.

    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.

    Great upgrade from the auto feed string head
    I was frustrated by the design flaws in the auto-feed head. My dealer recommended this head. I am VERY pleased. It is durable and the blades last for many hours of use which translates to months for what I use it for. The blades are durable but not indestructible. They are great on grass, weeds and vines but are brittle and will break against fence posts and trees. I have brick flower beds that I have to trim around. I have to switch heads regularly.

    This thing is a BEAST!
    I bought one of these along with my FS-85 brushcutter 16 years ago, when I was moonlighting mowing lawns. Both the trimmer and head are still going strong. I use a short piece of.105" line along with the knives, and can pretty much cut all day without having to change strings. The flail knives make quick work of high weeds along ditches, and doesn't seem to throw as much debris as my Supercut head.

    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.

    Fantastic Blade!
    I have the 8 tooth grass blade, and it cuts all my thick brush. When I first bought this blade, I thought it could only cut thick grass because it is a "grass blade", but it cut all my wooded brush just fine. This blade even cut some trees that had a diameter up to an inch.

    This is a CONDITIONAL recommendation!
    The success of your use depends upon what types of grasses/brush you are cutting. I found that the stringy/wiry grasses tend to ball-up between the blade & cutter head, resulting in your having to stop & clear out the mess. Also, this blade cannot be flipped over resulting in your having to spend down-time doing a resharpening. It does perform well in most regular grasses & the limited cutting surfaces keep the operator from over-feeding it into thicker woody material. It is not ... read more expensive. However, for overall usage...I recommend the 2, 3, or 4-tooth blade/knife options, mainly because they can be flipped over in the field with another sharp edge!

    Cuts like a hot knife
    This blade rocks. Cuts high grass like a hot knife to butter. I cut through saplings up to 2 inches with little effort. Grass is no match for this blade. It's like a lawn mower but with out the bogging or clogging factor!
