Well, I've had some clear user error issues repaired, like bent pliers and, blades loose from prying and smashed liners in used purchases.
Though I requested merely restoration to functionality, so I don't know if a repair with period-correct parts is free, it is after all partly about reserving collecting value, not just function, which the guarantee is for.
You could ask your importer and Victorinox. Note that if they have a local center they probably do 91mm, 84mm and 58mm but probably don't have discontinued parts, so with just sending it your importer would almost definitely just slap a new version on it to not have to send it to Ibach.
