Oh, THAT one. . .
I, too, was interested in that one. Haven't been able to find out anything about it recently. Carlos, the moderator of the Spyderco Gen. Info. Forum seems to be kept up-to-date, though. If you haven't already, it might be worthwhile to either post this same question on that forum or email him directly if his address is provided in his forum profile.
Just so you know--I believe they're calling it the S.P.O.T., for "Self-Protection Option Tool".
Wish I coulda helped,
