Extreme Pen — Episode 2: What I Carry

Don't look too quickly or you'll miss it (above).

It's a replacement ball point pen for the larger Swiss Army knives.

I keep it in my wallet for notes and what have you for when no one has a pen.

You wouldn't believe how useful it's been over the years.

70 mm (2.75") long and worth every penny of the $1.90 it costs.

I always keep a few extras around just in case but each one seems to last for years.

Outstanding technology at a very reasonable price.
