You should regularly clean and oil your knife to ensure that it functions properly. Follow the easy steps below.
When cutting or peeling fruit, fruit juice often runs down between the blades, sticking them together once it has dried. Open and close the blades in warm water several times and the tools can be easily moved again. When they have dried it would be good, but not always necessary, to apply a small drop of oil between the blade or tool shank and the spring. On the locking mechanism sometimes a drop of this excellent gliding oil could be helpful. Do Not put penknives or other multi-tools in the dishwasher!
When selecting knife oil, various properties need to be taken into account, including the legal provisions relating to the safety of foodstuffs. Some oils intended for pocket knives do not provide satisfactory lubrication or may even prevent the knife working properly (causing it to stick, for example).
Multi Tool Oil (Victorinox Art. No.: 4.3301)
The main features of this multi-purpose oil are:
neutral odour and taste, highly resistant to ageing, good wear and corrosion protection qualities, suitable for use with foodstuffs.
Re-sharpen using 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.
It's as easy and simple as that!
