Okay, okay, I know you think pencils are old hat and all that; I've got news for you. The bane of any mechanical pencil user's life is the inability to maintain a constant line profile. Technical drawers, architects, archive researchers and any one else out there who uses the ever useful mechanical pencil the solution to your problem has arrived! This mechanical pencil lead turns and presents the same profile each time you write with it. Wow, what more could your average spaceman ask for. Brilliant!
