If you have used any Champion Cutter brand products in the past, you know you are getting a quality product. This blade will clear blackberry bushes and similar patches like nothing you have ever seen or tried before. This unique style blade has the tips bent down so that they cut both vertically and horizontally. I won't try to estimate how much faster than any type of traditional blade ---- THERE IS NO COMPARISON --- The blade will come with an adapter ( washer ) so that it will fit any make of brush cutter that has a 25.4 ( 1" ) or 20mm arbor ( almost all ) . Blade is app. 12" long We also carry the blade adapter kit for those of you who are going to be running this on a Stihl. ( See our other listings ) We also carry several other types of blades for varying applications. YOU WILL NOT BE DISAPPOINTED IN THIS BLADE --- We ship priority and we ship quick  ( look at our feedback ) Please do not ask if this blade will fit on your specific trimmer. There are hundreds ( if not thousands ) of different brands and models. It is impossible for us to be familiar with everyone. I can tell you that the vast majority of string trimmers that are rated for a brush cutter blade will work with this blade ( either as is ( 1") or with the adapter ( 20mm ) arbor. It is your responsibility to find out wether this blade will work on your machine and what if any other fittings, deflectors, guards, etc. your specific machine may need.
