On advertising SAKs you will find all types of emblems, it could be hot stamped, printed or inlays. This can be depending on what category of knives used
but it seems advertising SAKs could have more variations. I am not always sure of it is an economy model just because of a hot stamp as so on or if printed is the same? In general for me when inlays are used it is the main line used. You will find all
types of methods used in history for the advertising itself.
The old economy line or elinox had inlay emblems too. So have that in mind. What i mean above is the traditional cross and shield. It is educating!
I will explain some of my factors for placing the 91mm advertising SAK above from 1990-early 1990s.The awl is a type that you can find until the late 1980s. The corkscrew is without groove. The tang
stamp backside got connecting lines (used until the early 1990s). It got a big V in Victorinox. Then it is the other designs that guide me into the 1990 sphere or time window. The most correct would perhaps be 1987-1994 maybe. Both the main line and advertising
line got several variations when the time windows are overlapping. It is very difficult to be sure. What I can say is that my experience usually indicates whenever advertising is involved that there are more variations. This is natural because Victorinox say
it themselves that advertising knives may have variations outside the normal evolution. Typically it is later by a couple years.
To conclude this today: To make a frame of solid factors can be difficult. As mentioned the best when you have advertising SAK is to have it as an advertising line knife even if the main line functions
or tools/designs are used. I have seen pure main line SAKs used for adverts and everything in between.
