I tried to view the message on the other forum, but got a 404 error.

However, as I read PL's quote, I understood it to mean that the Victorinox glasses screwdriver was modified to accept a flint rod.

The Vic glasses screwdriver is a tiny (about 1-1/4" long) slotted screwdriver with a grey handle grooved in a spiral to match the corkscrew on their knives. It twists into the corkscrew, is held in place by the scale when closed, and the blade of the screwdriver is protected by the rest of the corkscrew. It comes with the SwissChamp, & maybe a couple of other models, and can be added to any one with a corkscrew. Wearing glasses myself, I have one in all the SAKs that can take them. It may be seen at www.victorinox.com. Go to the products/pocketknives page, and look at the SwissChamp or TimeKeeper models.

Removing the shaft of the screwdriver & replacing it with a flint is a possibility, and I took it as what was meant.
