CRKT Guppie and Eat'N Tool Combo Pack

If you can manage not to loose the tool-bit attachment because of it’s week magnet(s), you might find this tool OK to carry on days you need it. Otherwise, it’s a little bulky for normal pocket carry. Put it on your belt and you will end up loosing the bit holder (as well as the bits). I did notice over time that the blade became loose and I had tightened the hex bolt as tight as it would go. You might be better off just getting a multi-tool.

will this go thru TSA security check at the airport?

has a blade so I highly doubt it.
