Here are three nice Wenger knives with advertising or company name.
Wenger 65mm and the 85mm category knife, I always have the collector curiosity
about what the advertising is for. I searched the internet on Biotrans 2009, it seems the convention was held in Switzerland in 2009 and is scientific related.
Optiswiss is a company in Switzerland
for lenses and glasses. The NailClip got the Wenger company internet address on. It is a NailClip 580 with translucent scales on. The Biotrans got the Classic 85mm main functions . No toothpick and tweezers in this black scale model. It is very
The Optiswiss 65mm got the basic functions you will find on the Esquire knife. During the last years more people collect advertising knives, there have always been collectors of
knives with advertising on, but more people collect them now. There are different areas people want, for example military or special company knives, one will always find knives printed and ordered directly from the factory and you will find independent companies
that made the advertising or print.
For me it is fun with any advertising or logo knives, it is a modern art. The impression i get is strong since it is a Swiss made knife.
