I don't see any weaknesses in the pliers, but I haven't put them through the test yet.
please keep us posted on how the pliers hold up during testing!

I'm definitely curious as to whether or not the plier head has been weakened at all. I haven't modified the plier head on any of my mods for exactly that reason.
This way I can simply replace the original plier head if any warranty returns would be needed in the future.
the people in the LM's warranty department can tell when a tool has been modified, even if everything is restored to the original configuration. I've asked them about it before.

in my opinion, when I modify a tool, as soon as the first screw comes out, I have
knowingly and willingly voided the warranty and forfeited the right to any future warranty claims on that particular tool.
