Office supply geeks around the world are abuzz over a new paperclip called the Acco Klix. The metal, jaw-type, multicolored clips are said to be an improvement over traditional wire and sheet-metal paperclips, although they are much more expensive (10 for $3.99).
Paperclips are classified in ECLA under B42F1, "Sheets temporarily attached together without perforating; Means therefor". The code for jaw-type clips is B42F1/00C.
Illinois-based Acco holds more than 400 U.S. patents for office supplies and equipment.
