From the early 60s until now is our known date on the magnifier glass from Wenger. The Delémont factory originated this tool on
Swiss Army Knives.
We have very little information on this and it would be nice if we could receive any information on this tool in the time period early 60s and downwards. We have some information
from the 70s and up. Or if you got a specific date of the introduction or invention on it please let me know.
You will find this tool with variations and modifications for different applications
and knives.
It works very well as a Jewelers screwdriver or magnifier tool for hobbies like postage stamps or miniature work. There is a variation on the small flat screwdriver tip as well. Models
with special tip part designed to open watch cases.
The one on the picture got a screwdriver tip that is handy for small flat head screws. The whole tool is a multifunction tool that may fit very
many tasks.
