Victorinox use brass rivets in their Swiss Army Knives and it is almost impossible to pull a SAK apart. The use of bushings is a very
strong design.
On the picture you can see the rivets that held a 91mm knife together. This knife has seen rather hard use. Sometimes this knife took much more force than the size and dimensions should
take.
Even so the rivets and bushings did not bend or stretch out of position and they are surprisingly straight. There are a few grooves in the brass from the steel functions or implements. This
knife was taken apart on purpose. Either the grooves are from sand/dirt or they are from the edges of the hole in the functions because of the twisting when using a screwdriver or other functions.
A
Swiss Army Knife got precision and it is a remarkable knife.
