Notes: "This slide rule is an historical oddity, in that it is a basic, general-purpose student slide rule manufactured in (!!) 2009 (price: $29.00). This is 30-some years after all the major slide rules manufacturers quit the business. Unfortunately, the ThinkGeek rule was poorly constructed and the slide was sticky. Purchasers didn’t like it, and they uniformly agreed that purchasing some other, used rule would have been a better choice. As best as I can tell, the Nanoline 1337 is the only model ThinkGeek manufactured."
