I’m not sure I understand marrying “edc” and “survival” but I see a lot of things of dubious value (in use or for the space they take up). I’d consider changing the following for better utility in real world situations:
Short lengths of cordage may leave you short…have at least a 50’ hank of something 500lb or better. If you needed to rappel a short distance (rambo cliff, elevator shaft, rooftop) then you can double that over and perhaps descend safely at least once. Anything at all works for lashing, so you could get some of the small ultralight cordage that takes up little space and have lots of that available (Lawson Equipment has great medium sized stuff, actually you won’t find better and you can get smaller diameter for the same or greater strength….zing-it and amsteel are both popular smaller cords).
Replace the mini with a full sized Bic and consider capping it or putting it in a tube so you don’t accidentally let the magic gas out while crammed in a pouch.
Add a blaze orange cotton bandana…better if it’s in addition to your hankie, else substitute it.
Add safety pins…two isn’t good for much but five can start to mend a longer tear in clothing, etc.
Add a couple buttons to the sewing kit.
Tiny amounts of duct tape aren’t good for a whole lot…heavy and bulky but more is better. Mostly the same for the aluminum foil, but a small piece like that could be used for fishing lures or shorting a circuit to make fire…not good for signaling and you have a mirror for that anyway.
Get a real compass…simple clear baseplate map compass doesn’t cost much and is actually useful with a topo map, provided you know how to use them together…but way better and also more reliable than those little button compasses of any type.
Dental floss can replace your sewing thread (mostly) and is almost better to have along than a toothbrush…the little freebies at the dentist that are in small round-ish tins are perfect.
Most serious of all….ditch the mini straw water filter. Or keep it but add at least something like a Sawyer Mini to the kit and a way to use it (bottle, pouches, a little tubing). And ALSO add some chlorine dioxide purification tablets (Aquapur and similar). If you have to draw water from ugly sources and/or around human habitation where sanitation and plumbing have failed, you will be dealing with more than typical backcountry bacteria and organisms with quite a high chance of viruses of various types. These filters will not do viruses, but the tablets will (and they will take care of nearly everything else as well). This is important…and those straws are a royal pita if you’ve ever used them, plus you will likely need to deal with non-pristine water so more surface area helps to reduce clogging and effort. You need a way to collect water as well……couple of gallon ziploc freezer bags are good to have and better than bottles if you need to collect from a very shallow source or wait for a drip in an awkward location.
Second most serious of all…ditch that gimmicky buckle whistle and get a real whistle. Bulkier, but if you need a whistle you want one that produces more sound at a better tone and takes less effort to achieve that. If you’re injured and need to whistle, you may not be able to summon the oomph needed to make the gimmicky ones work and they don’t carry well anyway. The “Storm” whistles are fairly cheap and any of those models is fine (except the sports referee ones). Takes up a little more space but actually serves its purpose.
Don’t discount sunburn and don’t rely on sunscreen for that (bandana can be slightly helpful for this).
You may be sorry to have that peroxide in there if the straw leaks. Actually, for the miniscule amount that is in any straw, the peroxide and alcohol both could be ditched (they’re single use anyway), and also perhaps consider the value of only 2 tables of anti-diarrheal and advil. Maybe put together a small add-on first aid kit instead. If you have diarrhea that isn’t just brief weird stuff from stress or whatever, then a) anti-diarrheal tabs may not even help, but b) you’re going to need several more. Same with advil…at least bring four so you have one single 800mg “hospital” dose, but that won’t last for long.
I think I’d ditch a lot of the stuff and very much reduce the redundancies, replacing with reliable and useful equipment that will actually work, and even move to a bigger pouch if necessary. Having what you really need and having it perform as needed is way more important than the joys of tetris with mini items to make a nice list of too many things that fit in a small space. My respectful two cents as one who made these things as a teenager, learned some of the folly, and later taught wilderness survival and simple wilderness first aid.
