SUL, Sal has mentioned that at least once a year, the Spyderco facility holds a "seconds" sale in the parking lot area that is opened to the public. These are knives that didn' t quite make it thru CQ. They are mechanically sound knives but have some (cosmetic?) imperfections. But Sal knows better than I.

PS- some seconds also show up once in a while on the 4 sale forums.
