- In December 2010 Victorinox manufactured a special-run of 50 knives with the the name Sea Pioneer. These knives feature blue Alox scales with the old style silver cross, and a top advertising panel with "Sea Pioneer" imprinted in white. Each of these knives feature a series number n/50 stamped on the main blade. This was the first knife issued in what would be come known as the Blue Marlinspike Series.
- In August 2013 Victorinox issued a special run of 150 knives especially for Siamese collectors. Each knife has red and blue scales and its engraving panel is enscribed in Siamese the 5th Rama (dynasty of the Chakri family). The blade is etched 2556 (2013 of the Gregorian calender) and nnn/150. The other side of the blade depicts an elephant and a picture of the king. Between the two, in Siamese, is the king's name, Chulalongkorn the Great. He reigned from 1868 to 1910 and was known as the Great Reformer.
