The Tool Pen, designed by Mininch, really isn’t a pet at all, but a multi-purpose screwdriver that you can carry around in your pocket or purse, or inside your vehicle’s glove box. The basic unit comes with six different commonly used heads, including slotted (flat), Phillips, hexagon and star-shaped bits. All are encased in a mechanical pen-shaped aluminum case that also doubles as the driver (the bits themselves are made from milled carbon steel). The basic Tool Pen can be had for $69 for the 16-bit set, or $75 for the full 18-bit version. Full details at www.mininch.com.
