From Case: To celebrate the turn of the century, we are proud to present a very limited edition of knives called The Twenty First Century Collection. This unique series of 50 of our most popular patterns and handle materials will feature a modified version of the new tang stamp which will incorporate "Case MM" (Roman numeral 2,000). It will also feature a specially-designed Case MM shield. Both the tang stamp and shield have been produced exclusively for this limited edition and will never be used again.
