After about a year of research I finally discovered the certificate of authenticity that was stuck between two gadgets from the knife: If you have the same problem, not knowing if this is a recurring fault, note that home It was between the barbecue and the chain saw, which, incidentally, are very useful to me (because the arrangement allows for cutting wood and then place it in the barbecue, everything has been thought, we can feel it, nothing is left to chance). So I finally got the certificate framed and hang it in the hall of my house. I assure you, the certificate is fairly small, it is only A0 (118.9 / 84.1 cm, a very common format for which the frames are easily available and cheap).
This knife has allowed me the last five years to build my house with the cement mixer, scaffolding, steel bars required for the development of reinforced concrete (attention, there are only 500), the saw metals and three backhoes it contains. My neighbors were first surprised, then this knife was a wonderful meeting vector, arousing the interest of the whole quarter, I am confident that many of my neighbors buy one, if not already done.
Obviously, in 5 years with a knife so convenient, it does not build a house. It also greatly helped me in my project deviation of the rotation of the Earth. Indeed, if we manage to unfold all its gadgets after each other and be buried with its base supplied with loader, we have a fairly stable base to reach the moon and so the hit for deflect the rotation of our planet. This had quite serious consequences that the media covered as natural events, including severe earthquakes and tsunamis. The equinoxes precession cycle is found also changed, which should gradually lead us to a reversal of the seasons. However, the cause will certainly be covered by the media in favor of my anonymity.
I invite you to buy eyes closed this handy Swiss Army knife and cheap, given its potential. It is to be seen as a short term investment.
