This model extends the very popular Yeoman model to four layers with the addition of the pliers; the main feature of the 91mm Mechanic. Victorinox first manufactured these models in August/September 2011, prior to this Swiss Bianco had assembled a couple of prototypes.
In addition to the Swiss Bianco version, Victorinox also made an unknown number of Yeoman Mechanics for the French company Heuliez. This version had the older style magnifying glass, no nail file on the hook and green plus scales with an inlaid Heuliez logo on the front, and a printed logo on the back scale. It came in a matching pouch made of green fabric, also with the Heuliez logo.
This was a small special run so it is very uncommon, and availability is limited.
Translucent ruby red Plus scales.
Green for the Heuliez version.
Only the Heuliez special run Yeoman Mechanic is known to have a different scale design. Note: This model predated the Swissbianco edition.
First regular scaled, generally available, models produced by Victorinox for Swiss Bianco in August/September 2011.
