So I was thinking of this and put this together.
The Phillips screwdriver came from a bike kit and I liked the idea so much that when I cracked the handle on a screwdriver, I pulled my torch and formed the handle thus. I was careful to keep the heat away from the tip.
The wood chisel came from my toolbox after I broke that handle.
the prybar with notch I found at a swap meet, then cut down to something portable.
I went to a woodworking store and bought the smallest drawknife I saw, then cut the handles down.
And a whetstone to keep everything sharp.
I have since added a small flat file and am thinking of a rattail file.
Nothing will make anything large but it will repair any tool or weapon I carry.
