The SOG CrossCut retails for around $20 and claims to include 10 tools. I got one off Ebay for a reasonable price and just received it today. Here's my initial thoughts:
Basically, except for the chisel ground knife blade, all implements at first glance seem useless. The scissors and spring mechanism, however, are exceptional, so this tool has found a spot on my keychain.
Toothpick - I can't imagine myself walking out of a restaurant with this toothpick and CrossCut hanging out of my mouth. It's not a sharp ended pick, so I don't think it would be successful in removing steak from my teeth.
Nail File - I honestly tried, but could not get this nail file to work on my fingernails. Even if it did, the rectangular nail nick cut into it for opening purposes acts as a stopping divot to whatever you are attempting to file. Perhaps this file would work on things other than fingernails, but then, it's awful short.
Tweezers - First of all, the ends of these do not meet up, making them competely useless. I wonder if this imperfection is due to its being made in China
Flat Driver - I did not test this, but it looks like it should work Ok.
Small Driver and Bottle Opener - The small driver is too thick to fit into any small screw slots that I've come in contact with. I can't imagine a use for it. I did not test the bottle opener but will assume that it works.
Scissors - These work quite well on everything from Clam shell packaging, to plastic, to paper and even thick stock. I very much like this functionality and therefore am willing to forgive the rest.
