Some were made this week actually.
I started with the one. And it lacks features I use. So I made another to see if I could and then one with the features I use most.
Wrench, screwdriver, bottle opener and mini prybar.
And it kinda spiralled out of control.. The new improved version hasn't been created yet.
Material could be mild steel, alu or stainless. I use them all if I have a chunk.
Most are either test models or work in progress. Still trying to make a wire stripper that works, thatis quite difficult.
The perfect small one piece pocket tool is not something so easily invented. Lol!
