Picks: Tap guitar picks have become collector’s items (one is included with the CD-ROM and laser disc reissues of "This is Spinal Tap").

David: "It didn’t slip because it had those grooves that were matching up with yours." (HS) In the band’s early days, Nigel used picks made in Hawaii from macadamia nut shells. (HS)
