Introducing the Lotus Titanium Pen – another sleek, innocent-looking pen that has more to it than meets eye.

Like the Titan, it's made of solid titanium, so it's tough. It also takes standard Parker ballpoint-style refills. So, it's a good pen to carry around every day for general use.

When it comes to the Lotus's tactical function, there's actually a weapon hiding under the small cap at the back end ... the 'Lotus DNA Catcher'.

For those of you who haven't heard of a DNA catcher on a pen – it was news to me too! – it's a sharpened crown which not only functions as a tool for striking and wounding assailants, but is designed to collect their DNA for identification later.

Slightly disturbing ... but hey, a good idea!
