Query: Extremely Poor Quality/Dangerous

These do not appear to be authentic Sabatier knives. They appear to be knock-offs and are dangerous to use as they are DULL even after sharpening. They are VERY HEAVY and unbalanced. They have little if any cutting ability. They come from China. The holding block barely has a Sabatier stamp on the front. I would not recommend these knives even if they were free.
