The PHX-1 design tool set is a wonderful drawing-system set that consists of a ruler, a pen encasement and a hobby-knife all contained in a bamboo carrying case. Designed by Beijing-based designers Chadwick Parker and Joe Hung of Big I Design, this system was meant to represent the performance quality of their favorite pens Hi-Tec-C, Uni-ball Singo ink and X-Acto. The stainless steel form is equivalent to the cartridges of these brands and also features a hobby-knife detail included on the opposite end of the pen. The ruler is full of multi-functional elements since its comprised of seven different measurement systems within its makeup and even operates as the top of the bamboo case. With the 2011 holiday season here, this is the perfect gift for your designer friend.
