These models featured 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 for Siamese collectors. Each knife had red and blue scales and the engraving panel is enscribed in Siamese with the 5th Rama (dynasty of the Chakri family). The blade is etched 2556 (2013 in the Gregorian calender) and nnn/150. The other side of the blade depicts an elephant and a picture of the king.
