What is a s and w swat first millennium run?

S&W S.W.A.T. First Millenium Run is a series of folding knives.

S&W stands for Smith & Wesson; S.W.A.T. stands for "Special Weapons And Tactics", which is the moniker American police department paramilitary squads go by.

"First Millenium Run" is a designation S&W put on the S.W.A.T. line of knives just before Y2K. The second millenium of the common era was to end, and the third millenium of the era to begin on 1 January 2001, so in 1999, S&W put that designation on knives becaus of the common misconception that the 21st Century/Third Millenium would begin in 2000. It was to be the first run of the new millenium, rather than suggesting that Smith & Wesson was making these knives betwen 1 and 1000 A.D.

As I understand it, they're still making these knives (they're very good knives for the money!), they just don't have the "First Millenium Run" etched on the blades any more.
