26. Adding a needle or straight pin to the handle
In 1991 Victorinox began putting a straight pin on certain models,
like the SwissChamp and the Compact and the Plus Models of Climber or
Huntsman. Wenger does not offer a pin. To add a pin or sewing needle to
any SAK that has backside tools: Open the corkscrew or phillips driver;
the pin will go into the slanted surface of the scale, 2 needle-widths from
the outside edge of the scale and right against the alox liner, as on the above
knives. Choose a pin or sturdy needle; hold it near the head with pliers,
heat it in a flame (it only takes a moment to get it red-hot), and, with the
pin parallel to the knife, press the point into the slanted plastic surface adjoining
the liner and immediately pull it out. The pin will be coated with
red plastic which you can burn off in the same flame. When cool the pin or
needle will fit in the hole you have made. Close the corkscrew.
It can be seen in a translucent SwissCard that the slot for the
straight pin is curved, flexing the pin slightly to hold it in place. The
pin/needle SAK retrofit depends partly on the closed corkscrew to hold it
in place.
