I am not even really sure if I would want my knife to come as part of a package.
I tend to keep in mind that these are just pocket survival kits too, so a decent disposable blade might be a fair option.

(Maybe a small Olfa style knife like CK1 or CK2 would do it. http://www.olfa.co.jp/en/body/kind/8_p2.html
These are small but fairly solid and they are resharpenable.
They might need to be redesigned a bit to make them more suited to our needs.
Maybe a smaller or thinner version.
Maybe a button type slider instead of a round nut on a screw, or maybe just an easier to grip and larger nut with nylon or something to make sure it does not vibrate loose when traveling in a car.
However, it is a fairly good and simple design to start from.)

I am sorry if I am sounding a bit of a sour note here, but I am just simply addicted to reality.

One of the problems with going too small and with trying to do everything is you end up with gear that really does nothing.

I would rather have a good small pocket knife on me, in my pocket, than a fancy and pricey miniskinner in a plastic bag only intended for emergencies.
I am far more likely to need to cut a piece of string, strip some insulation off a wire, or slice open a pant leg than skin a deer.

(and yes, to most of us price does still matter.)

Just an afterword here:
Two rules I have learned about kit is to keep it simple and keep it functional.
You certainly do not need to be trying to figure out how to use gimmicky stuff in the dark when you are cold, scared and confused.
Fiddley stuff tends to break and lose parts too.
If your kit is full of stuff that dies or fails to do what you need it to do when you need it, then it is just junk and it does not matter how well it was engineered or how finely crafted.
Most of the rest of the kit does manage to be simple functional and versatile.

A good design is a functional design. Everything else comes after that.
