very good product

There are 2 different styles of blades. You get 4 that are straight, angled blades and you get another 4 that are curved blades.Both styles of blades easily replace the blades in my trimmer. The holes in the blades match the anti-slip guides of the trimmer.The blades work well, trimming grass and weeds.

I couldn’t use them. They didn’t fit like they were supposed to with the weedwhacker i have and I couldn’t replace them because I didn’t have a printer at the time. So that was a waste for me.

I recently got a cordless weed eater that came with a sawblade, string, and a couple edging type blades, but was concerned about the proprietary mounting system since I had seen no others with that design. Looking for extra blades I found a set that seemed to have the same (distinct design of dual half-moon tabs) mounting system (see pics). I ordered the set to try.When they came in I removed the saw blade and put one of the edging blades on to see if it fit and it did. I used the new blade to edge my driveway and street front areas. I was able to edge the entire area, but as you can see from the 2nd pic, the blade wore away fairly severely from the infrequent contact with the concrete of the driveway and curb. I could see sparks fly each time I made contact, but didn't realize the blade was being eaten away so quickly. Since I had been edging with string before, there was not a clear path like there is now. Next time I edge with this I shouldn't be hitting the concrete as much since I can see path now, but the wear still seems a lot to me.I have used a metal edger before and the blades were much thicker than these, but this is a weed eater not a dedicated edger so it doesn't have as strong of a motor. I think if they used a heavier blade it would not be able to spin it fast enough, but it could also be the steel the blade is made from so I took of 1 star for that since it really seems excessive wear for edging about 120 feet total.I also have to cut my grass in the back yard with a weed eater since I put up a fence and cannot get inside with my lawn tractor due to the pool. My regular one only uses string so I wanted to try the blades to see if it was different. Wow, I wasn't expecting it to be that big of a difference.When I use the string cutter on my old weed eater, it cuts the grass quickly and doesn't bog down. I can do the entire back yard in about 30 minutes. Using the new weed eater with the metal blade took me a little over an hour and it was much harder. The grass is thick and the metal blade would get bogged down frequently and stop so I had to keep starting again. The other difference is the metal blade is only about 6 inches where my string cutter is about 9 inches and doesn't bog down even in the heavy grass, but I have to bump to add string as it wears.I think the difference is due to the motor on the new one which seems a little smaller than my string trimmer so I didn't take off for that. I use the saw blade trimmer for clearing some areas where we have vines and brush growing and it works great for that where the string trimmer won't cut them down. Now I can also edge with it and get a clear demarcation instead of having to constantly bump the string out more as I edge. The saw blade will cut up to about 1 inch and these edger type blades will cut up to about 3/8 inch, but are faster so they will also help with clearing the smaller stuff quicker.Overall, I am happy I found blades that fit the new weed eater so I have spares, but there is doubt as to the durability of the blades. They held up ok for just weed eating, but for edging it was severe.
