The Porsche Series was one of Wenger's Elite Series and done in conjunction with Porsche's design shop. The knives featured sculptured handles that were originally sold as Ruthenium, but which were actually zinc coated with titanium color.
("Regarding our Porsche design Knives, we confirm that the scales are not in ruthenium. The colour of the scales look like ruthenium but they are made of Zinc and coated with titanium colour. " Claude Kottelat, Chief Technical Officer.)
There are four models in the series. The Porsche Design Original ( Traveler ) was introduced in 2002, with the other three in 2003. The knives were discontinued around 2011-2012. The knives were basically standard models. The Multi Tool was based on the Pocket Grip, but has a different combination of tools.

Around 2006-2008 a special version of the Original was produced with black PVD-coated blades and handles. Known as the Cayman S or P'3700, this was part of an accessory kit that included watch, sunglasses, etc, and which was included with the Porsche Cayman S sports car. It appears that 777 knife were produced for sale with the cars; with an additional unknown number made for sale by Wenger. Wenger apparently sold both black and silver versions under the P'3700 designation.

At some point there was a slight change in the handles. The 'Porsche Design' logo was shifted to the left and a P'37** series number added. This does not appear to have affected the European names or catalog numbers of the knives.
