This really makes me curious, Lezyne Stainless-20 has a separate tool -- tire lever (however I don't see clearly on pictures how it looks like). The specification of Stainless-12 does not list tire level, but judging how the chain tool looks like it seems it could be used as tire level (unofficialy).
So maybe I rephrase my question to be more precise -- did anyone successfully (without breaking/bending the tool and cracking the rim, etc) use the handle of chain tool (of Stainless-12, lower brother) as tire lever?
Once again: I am asking about version -12, not -20!
Update: Just to avoid any misunderstanding -- Lezyne chain tool handle:
