Query: Most Amazing Knife Ever!!!

This knife is sooooo sharp out of the box that it was astonishing. I laid the knife on the cutting board with the blade up, I dropped a roma tomato onto the blade from about six inches above the blade and it cut the tomato in two!!! If you cut lots of vegetables or boneless meat then this is the knife that you have to have.
