I bought one on a whim, and I like it OK. I didn't need it, but it was cheap and seemed like it might be sort of neat. I was right, it is sort of neat. I don't specifically have a use for it, but it is a neat little knife for the collection. I doubt I will ever carry it in a survival tin. It actually carries pretty well in the pocket, though it will never replace any of my normal EDC pocket knives. Really, the nicest thing about it is that it is small enough that I can add an additional blade to any of my kit (fishing vest, upland vest, EDC bag, etc...) with virtually no cost in space or weight.
I would like to buy a quantity of that exact cord used on the knife, but am not sure what it is called outside of "Nylon Cord". Please help the dummy if you can!
