If you look on the other side of the 85mm blade towards the shank or tang you can see the backside grind is different from the main side. This is because the grind and tang stamp with the emblem
is the face outwards on of the knives.
Also the backside grind got variations…
On my knife it is just the main side two curves that are different; the backside grind is more traditionally but not completely either.
seems that Wenger change the appearance on a regular basis. It does not go too many years before you will find grind differences and changes in the emblem. From before I have researched the tang stamp itself with the obvious differences in the crossbow. The
placing and depth of the complete stamp must also be into consideration.
Every few years Wenger changes important design factors. I noticed that the tang stamp could go unchanged for a long
time until I used a magnifier to see that the modules were absolutely not the same. It may look the same and they are original but different.
I would also like to mention that there must not be any doubt that Wenger changed the appearance on a regular basis. The evolution on Swiss Army Knives is seriously a factor that this Company implemented.
Production variations can sometimes be so that where the stamp is placed and minor grind differences can be because of the production only. The tang stamp may sometimes be placed different just because
of more random production. There are an enormous amount of blades made.
It must also be seriously taken into consideration that Swiss icons and symbols are protected by law and the Factory
implements safety precautions for this.
I can guarantee that there is a code sometimes.
The knife I have shown on the
pictures got so different grind and details that it is important to research fully.
