A question I receive regularly is about what makes up my EDC kit. The first article I wanted to publish was about my pen. This is no ordinary pen. It is a magical pen that accepts over 200 different types of ink refills (roller-ball, ballpoint or D1). It is a beautiful pen made from aircraft grade titanium, which makes it super durable, light and incredibly beautiful. 

I have used hundreds of pens from a cheap BIC all  the way to an exclusive Montblanc. After everything is said and done, the TI Arto from Big Idea Designs is the one I chose to carry everyday (at work, during travel or at play). 

Why? First this wonderfully designed and carefully crafted pen accepts over 200 different types of ink refills (without hacking or modification). This means I can buy ink refills anywhere in the world and know it works. It even accepts the Uni-ball Signo DX without any modification. This is a highly prized refill by pen lovers worldwide but it never fits into these pen bodies. It works wonderfully in the TI Arto. How? Because the creative team at Big Idea Designs created a cone head that tightens as you screw it and therefore can securely hold almost any type of pen head in place. This internal compression cone is what makes this pen stand apart and is the secret to how it can accept 200+ ink refills. It is easy to use but will require a little fidgeting as you adjust it (when replacing the ink).

It is built from titanium which means it is extremely light and durable. I carry it in my wallet pocket along with a lighter and aluminium plate wallet and it has held up well. 

Overall I highly recommend the TI Arto. It will be a useful and beautiful part of any EDC kit delivering a lifetime of use.
