There, he and the cutlers union he formed produced the finest steel cutlery, finished with the now-famous proprietary edge preferred globally by professional and home cooks. In 1891, Karl supplied the Swiss Army with its standard issue Soldiers Knife and in 1897 with the Officers Knife. In 1921, after the death of his mother, Victoria, and with the advent of stainless steel, then known as inoxydable" and used in the production of his cutlery, Karl changed the name of the company to Victorinox. It is from those humble beginnings that a worldwide icon was born.Today, Victorinox is still owned and operated by the Elsener family, and both the company and family still resides in the small village of Ibach, Switzerland. Care Tips for Swiss Army KnivesThe various tools are manufactured from high-quality steel with precisely tuned features that are essential for the particular application. The steel is tempered, annealed and polished to achieve the necessary hardness and provide optimum resistance to corrosion.SharpeningTo re-sharpen your knife, use a whetstone at an angle of 15 20. This will result in a cutting angle of 30 40. If sharpening on a grinding wheel, always cool with plenty of water to avoid excessive temperatures and the resulting damages that may occur.CleaningAfter youve used your Swiss Army Knife for all of its various applications, such as cutting open numerous boxes, you may notice that the blades begin to stick together. Opening and closing the blades in warm water several times will allow the tools to easily move again. Once they have dried, it is recommended, to apply a small drop of oil between the blade or tool shank and the spring. To optimally maintain the locking mechanism, periodically apply a drop of our recommended Swiss Army Knife Oil. Never put Swiss Army Knives in the dishwasher.
