The Tinker Swiss Army Knife by Victorinox is your essential travel tool for any adventure or task. With 12 meticulously engineered functions, stainless steel construction, and Swiss-made precision, this compact tool is equipped to help you build, hack, or fix nearly anything. Featuring 12 functions including a large blade, small blade, Phillips screwdriver, can opener with a small screwdriver, bottle opener with a large screwdriver and wire stripper, reamer, key ring, tweezers, and toothpick, the Tinker is designed for versatility and durability. Its stainless steel components are tempered, annealed, and polished to provide optimal resistance to corrosion and ensure long-lasting performance. To maintain your Victorinox Swiss Army Knife, re-sharpen it using a whetstone at an angle of 15°-20°, ensuring a perfect cutting angle of 30°-40°. If using a grinding wheel, keep it cool with plenty of water to prevent damage. For cleaning, open and close the blades in warm water to loosen any sticking, then apply a drop of Swiss Army Knife Oil between each tool and its spring. Avoid dishwasher cleaning to preserve the knife's quality. The heritage of Victorinox dates back to 1884, when Master Cutler Karl Elsener opened his cutlery shop in Ibach, Switzerland. With excellence in steel cutlery and a reputation for the finest edges, Karl supplied the Swiss Army with the Soldier’s Knife and Officer’s Knife. Following the death of his mother and the advent of stainless steel, the company was renamed Victorinox. From these humble beginnings, Victorinox has grown into a global icon, still owned and operated by the Elsener family in Ibach, Switzerland.
