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.
