Che-Wei Wang and Taylor Levy of CW&T love the Pilot Hi-Tec C pens almost as much as I do but they went the extra step and drew up plans and prototypes for stainless steel housing and sleeve. The sleeve doubles as a ruler with metric and imperial measurements on it. Right now, the team has received lots of funding through the Kickstarter program so let’s hope that this amazing unit will be available soon! (via Pen Type-A Kickstarter)
