The full number on the green Hunter is 0.8873.4.
This knife is going in my collection and therefor I will not test it.
The modifications are interesting and there is another small difference and this is the small or slightly lighter spring pressure when opening the blade. The blade is manually opened and guided by the
slip-joint spring. The blade is locked when fully out. The weight of the complete tool is around 100 grams and the new modified SAK is actually one gram more heavily than my old.
update
Slip-joint
The mechanism is a slip-joint mechanism if we do not take into consideration the locking of the spring in the out position.
The blade is held in place in the out position by the spring regardless of the lock. It is held in in position by the same spring.
The locking of the spring is very interesting and it is
a different mechanism than one would find from other Brands. It serves the function of locking the blade for preventing accidental closing. A longer blade on this type is we should call it slip-joint would need a lock; if not the spring pressure must be much
stronger for a certain safe functionality. On a pure slip-joint mechanism the use of longer blades would be different.
The changes on the 111mm slide-lock category are just modifications
but improved as I see it so far and interesting. It would be fun to see the mechanical drawings of the lock itself to see.
Slider update
The slider
I can add that I can see part of the slider moving but just barely between. I suspect another detail with the new spring for the slider and this is that it is not only preventing dirt and substances. I suspect the slider is locked in a way that it would not be possible for it to collapse outside the spring.
Conclusion
The new changes or modifications are as i see it becasue of the Victorinox constant quality improving!
