Hello there, I was in the Swiss army. As a recruit ( 1983 ) I was issued a soldiers pocket knife model 61 ( AKA Pioneer ) and a bayonet for my Stgw 57. Most recruits quickly bought a second pocketknife, one to use and a second one to present at inspections. As an artilleryman ( M 109 )the bayonet stayed in the locker but the pocketknives were always handy for opening tinned rations ( mmm, compressed meat ) and to take apart our rifles or zero them in. I also had ( and still do ) a Gerber Guardian 1 because if you have to shimmy up a tree to cut the ropes holding the cammo net a double edged blade is a lot faster. Interesting fact: on the inside of the Stgw 57 bipod there are graduations. You pass a length of string through the hole in the pocket knife. open the blade, dangle it from the bayonet lug, and determine the trajectory for rifle grenades.
