JS 2 I bought this product thinking that It is a typical KTC Quality Product. But, this product disappointed me. After using it to change the sway bar end links on my car the tooth got damaged right away and I couldn't use these anymore. I had to use a triangular file to sharpen them again.The pictures are taken after sharpening them with a file, you could have Imagined what they would have looked like before.My advice: Only buy KTC Products If they are made in Japan.
