if you cut a piece of fish into two identical pieces with the same knife (lets say a victorinox), but serve it to a kkf nut (who isnt aware what you did) and told them the one on the left was cut with a shig and the one on the right was cut with a richmond, they would tell you the one on the right tasted like crap and that they can see the cells are shiny on the one on the left. someone prove me wrong!
