IMO, the easiest QR assembly
does indeed require the user to use the lever as a wrench. DT-RWS skewers,
DT Swiss - RWS Road steel, are a simple screw to close and unscrew to open. No need to check for tightness after a lever is thrown. Eliminates the if not tight enough syndrome of having to open, tighten nut and close again.
In other words, dummy proof.
