Now that folding box cutters have become more available, I have been carrying one for the past few months. Mine has been very useful for my everyday tasks in an urban setting: very sharp, easy to maintain, can be used for scraping glass and warn out automotive gaskets, remove slivers, cutting boxes, etc. However, I too have been wondering about how useful they would be in a survival situation. As mentioned before, they are great when they are sharp, but dull relatively fast and almost instantaneously loose their edge if they get wet. Another complaint I have about them is their usable blade length is quite short, only about 1 inch. Anyone else have any other ideas or comments on this subject?

Thanks,
Rio
