The bloodline of the Caly family touches a great number of knives in the Spyderco line that aren't necessarily "Calypsos" - I'm thinking of the Save and Chaparral in particular. But you can also see design cues - "genes" if you want to carry forward the family analogy - in knives like the Domino, Squeak, Chicago/Cat, Urban, T-Mag, "S", and even the SuperLeaf.
Nice picture, Phillllll! That's a great collection.
