Interesting how they can claim that you can create a TSA friendly multitool for traveling. While that might be interesting hype, I wouldn't want to risk my $80 tool and resulting trip to Guantanamo Bay on the whim of a TSA agent. They tend to err on the side of caution, and I doubt they would look too closely at what implements are included on the tool before dropping it in the confiscation box.
Interesting concept though. Still, I think a better bang for your buck in the interchangeable tool market would be the
