This model is a collaboration between Victorinox and Swiss Bianco. It is based on the Firesteel Soldier from Mr Horst A. Brunner, an well known Swiss knife collector who is no longer with us. The Firesteel Farmer offers the same combination of tools as the Farmer with the addition of an external piece of steel used to produce sparks. The firesteel attatchment was made from Mr Fischlin, hence the fish stamp on the steel. This knife is a unique piece that it was made in October 2010 and they won't make this color combination anymore.
