Welcome to MTO! Victorinox will most likely repair it under its warrenty. Where are you located?Or you can find another 58mm SAK with an intact spring to take apart for parts.Thats pretty much the two options available.
A third option would be to purchase the spring itself. There are spare parts kits from Victorinox (although you may not need as many) and you may be able to find a seller which could provide you with just 1 or 2.Oh and yes, welcome to the sak rabbit hole
