This is an opportunity to own the rarely-available Victorinox 9.6100.1 Tool for Changing Scissors' and Pliers' Spring.
A tool of craftsman-quality, supplied in its own wooden storage case, this tool contains a steel 'anvil' for holding your Victorinox knife, and a selection of tools for driving out the old spring and replacing with a new spring.
The set is complete with a number of replacement springs and full written instructions in English.
These tool sets are new-old-stock and don't come along often, and would be the ideal complement to your knife workshop and Victorinox collection.
The knife shown is for illustration and is, sadly, not supplied.
