That was my plan; got a set and figured I’d throw out the pile eventually.

But when I tried using only my set keys, it turned out some of my gear has specialty sizes I can’t open/tighten with my set keys.

So now I’m MORE paranoid about hoarding all the Allen keys.

The free ones they give you are made from the cheapest metal and to poor tolerances. They're literally the bare minimum to put together whatever they came from. They'll potentially slip and round off if used heavily. Good quality ones are made from carbon steel and will hold their shape.
