Originally, I purchased a Juice Pro at Costco. the JP is way too big for pockect carry, but has the most tools. I now keep the JP in my pack, fatboy, or locked in my desk drawer. I bought the CS4 about six months ago, and it is perfect in a front pockect, or back pocket. The CS$ is my EDC pocket tool. I too have a Victorinox mini screwdriver in the corkscrew.
