The Mora Floating knife 13686 is a remarkable fixed knife. The handle is made from cork. As such the Mora Floating knife will, yes, float when you drop it in water. This knife was specifically designed by professionals in maritime surroundings. Think of fishermen, men in the offshore and the crew of a ship. In those surroundings a good knife is key. The blade is made from stainless steel. This means that it won't rust easily. At sea, however, you will always see traces of rust in time. That is why it is important to clean the knife after use with fresh water and occasionally add a drop of oil to the blade. The Mora Floating Knife comes with the famous plastic sheath. Even though Mora is known for its excellent production quality it is, of course, obvious that a knife with a handle made from compressed cork is less sustainable than a handle made from hard plastic. Fortunately this knife, like all other Mora knives, is very affordable.
