The Duchess is a rare 58mm Victorinox model with a unique design. The handles, or scales, are what collectors call a dogbone shape.  The logo is also different, featuring a white Swiss cross in a circle that is centered on the top scale. The reverse side of the blade has deep Victoria tang stamp with crossbow in the center.
The unique shape of this knife was apparently developed for those unable to open a standard pocket knife with their finger nails. This shape allows the tools to be pinched and pulled open.

Discontinued model.

• Small pen blade

History

Probably one of the earliest known Alox handled knives. All of these knives are tang stamped with the Victoria mark on the back of the main blade. This knife has evolved into the Companion.
