SOG Access Card 2.0
2.75 in x .08 in
Here's what other sites are saying:
The Access Card 2.0 doesn't grant admission into top secret facilities, but it does give a sense of security! This minimalistic sliver of a knife (3/16" thick without the clip) won't take up much room in your wallet, pocket, attached to a ballistic vest, or around your neck. The 2.75" formidable VG-10 blade opens and closes with one hand like a magic trick and locks with our famous Arc-Lock. Although every bit of excess weight has been engineered out of the Access Card, you will be surprised at the power it conveys.
