Victorinox Deluxe series

This series contains 6 58mm "Bijou" knives with enameled scales, or in simple words...glass scales... These scales have each another pattern, going from blue marble to plain black. They were made from the early eigthies till 1999 and are discontinued. While the knives are actually 56mm, due to the fact that the corners are squared off, they are still labeled as a 58mm. From 1987 on Victorinox added the shield on the scales, so this serie should be made before 87... I recently bought four of the six available in a brand new condition. The one I definitely want to add is the gold one, but this is gonna be difficult since this was the first one to be sold out completely...
