I would make my own. I have my homeade kit which I constantly improve on and change. I am able to tailor the kit to suit my needs and fill it with the highest quality items I can find. Over the years I have learned what works, how it works and if I really need that item or not. It is small, light and effective. I would not expect this kiit to keep me alive for years but it will provide essential items to survive in comfort until I can either get out or get rescued.
I do not keep a knife in the kit anymore, I used to keep a SAK, Farmer in the kit, but prefer to carry it in my pocket now instead. Depending on the trip I am taking, I will either carry a locking SAK, a Swiss Tool or the Farmer. I also always carry a Grohmann #3 Boat Knife, folders are handy items but not strong enough for serious survival use. The #3 does not weigh more than the SAK locking folder.
My rules when making up a survival kit are simple, will it work, can I use it properly and do I really need this item? There are many handy items you can pack in a kit, but will they actually aid in truly surviving an emergency? You need to be your own judge of that aspect.
Have fun with the kit project!
