David Cyr and Kevin Passon are known far beyond their native countries for their extraordinary, extremely practical tactical pens. The Böker Plus Bit-Pen also serves primarily as a high-quality writing instrument, but also has a useful additional function. The short handle body is made of lightweight aluminum and houses a bit holder that is hidden under the top cap. The practical bayonet mechanism is also convincing, as it significantly increases the comfort of use. There is no need to unscrew the cap or the lead for writing. The Boker Plus Bit-Pen counteracts the annoying click of nervous users of plastic pens thanks to the rich sound from the all-metal bayonet lock. Thanks to the stable clip, the tactical pen is always at hand. It is compatible with the Lamy M-22 cartridge and comes with a double-sided Torx bit (T6 and T8).
