Victorinox and Wenger philosophies
Around 1982-1983 Wenger introduced a new safety feature. This new design would be for
comfort and for evolution. Everyone knows the feeling when the flat screwdriver accidental close -therefore the push lock safety feature was made.
It works just by pressing the flat screwdriver towards when
using it. It will lock into the notch in the spring.
Wenger did use this patent on more functions in the years after, on the Phillips and combination tool as well. It is a very smart invention and like on
every Swiss Army Knife it does require full precision in the production. Not easy to make!
When did Wenger introduce this locking on the Phillips? It is a good question, it is always more difficult with Wenger,
what I do know is that I have seen this on knives that I would suggest are from the 1986-1988 period.
In 1985 Victorinox introduced a flat screwdriver (with the cap opener and cable tool) that could be used in 90
degrees. Then in 1999 a notch to prevent accidental closing was made, when the tool is fully out it will prevent it or make it more difficult to accidental close.
It is part of the evolution and comfort of a knife
and requires very high precision just like on the Delémont type.
Both brands developed this on more than one function.
A 90 degree function
is old in the history of the Swiss Army knives.
The point is that the two brands philosophies are very different.
