New Russian Knife Escapes Metal Detector
This knife can be easily stored in a bag when we board on a plane without being detected by metal detector. This knife is made by a russian (Bob Basset) from sapphire, a solid stone which is also used to create scratch resistant glass on swiss watches, while the handle is made of bone. Only diamonds can defeat its hardness. Therefore to sharpen this knife, we should have a diamond to do it. This made it quite expensive.
