>Can you back up this purely qualitative statement?
yes I have eyeballs and can read the product description, plus the fact you have personally broken like 3 now, and others online have had similar issues. The lever is physically too flimsy a profile. It would maybe work with tool steel rather than 4140 but even so really needs more material for longevity.
>have you looked inside or seen a good cross section
you don't need a cross section, the lever is exposed for all to see. You'll notice the lever has a significantly shorter moment arm as well as basically the opposite sectional profile, being thickest in the direction is rotates.
