THTENKST-120X KST2040-06 Trimmer Replacement Blades Compatible with Kobalt KST 120x-06 and 40v Cordless String Trimmer 18 Pack (Item 1520463,506892,808667)

These trimmer blades are great. I use these to trim the thicker weeds. They are durable, and strong blades that work well. They are easy to replace and use. A well made product and a great value. I highly recommend.

I first started using these trimmer blades a year ago. I like them much better than the regular trimming line. These blades are for the replacement head that you order separately. The new head assembly installs in minutes and replacing a worn blade is just as easy. The blades are strong and durable, just be sure to not hit the fence or poles because they will wear down much quicker. Overall, I'm satisfied with these blades and will recommend.
