All these information is my own experiments and thoughts.
The spring mechanism continues to interest me and it is very advanced. The possibility
to open all the functions at the same time or hold all the functions in an open position that will put maximal strain on the spring. There is pressure in a Swiss Army knife and on the internet you can find some information on this. This pressure can be very
high. I did experiment and I did feel this pressure from the spring when all functions was in this maximal position. For me the notch to prevent accidental closing did put very much strain on the system. The spring hurt. The precision in a SAK is very high
and it is in the Victorinox philosophy that the knife is always in the elastic region. To open all the functions at the same time is in their philosophy. One should never leave the functions over time in these positions. This is why as a collector i always
only open a few functions fully when cleaning and so on. This is only to be gentler on the mechanism like I explained before.
For me there is a special interest with the floating spring and its three
functions because this is the evidence of a SAK. For me there is a link between the rivet for the awl and the center rivet for the floating spring. The precision of the orbit for the notch in the flat screwdriver is important.
The spring on this layer is a very multifunction spring.
