About this 3D model
This is a model of the Heaven Sword from the Chinese Drama Heaven Sword and Dragon Sabre which can be used as a letter opener. Simply print the model twice, add some colour and glue the halves together. For more details and pics on how I printed it with a Solidoodle 2 check out my blog: http://www.thekingsofthings.com/2013/07/heaven-sword.html .
