Soap holes on the card
Two holes have been drilled here to store a bit of soap, just enough to wash ones hands before eating something. Note that the handle of the tweezers appear on the picture to to contextualize the little soap hole added on this Victorinox card. By the way it's amazing how many little spaces can be used on this Victorinox card, so the problem was rather what can I use all these holes for ? Up to know : soap, floss and paints.
