Aaanyway...

Thanks for all the feedback. I've decided against getting one or two more and instead opted to separate this one: I put the fishing and sewing "kits" in my long-term BoB/outdoor ruksack, the case in my class bag with some cotton (don't have Sparklite and my survival budget is pretty much done for the year) and added the wire saw to my EDC. I don't carry a pocket knife (not in my pockets, anyway), so it's better than nothing (and it is better than nothing, judging by my own test results). My only concern is the fact that the wire saw could be deemed a "dangerous object" if discovered...

P.S. About my EDC: I do carry a button compass and have swapped my shoelaces for paracord. That's almost 40 feet of 50 lbs line.
