Just a quick note to be a piece of shit, but high-strength epoxies used in metal bonds generally require consistent and high pressures in addition to high-temperature curing to set.

Moreover, "oh well this bond is strong in this one case" means nothing and is a sign of dangerous ignorance.

Shearing force is not impact force is not tension force.

That is not how rigid body dynamics works.

If you give someone a "safety device" that is faulty and they die not just as a result of its use, but in connection to the false sense of safety associated with its use?

You are culpable for some responsibility for their death.

That is what malfeasance is.

If you're gutsy enough to pose with your technicolor guns and talk big games about fucking around and finding out, you're gutsy enough to deal with someone being a fucker about you potentially wearing a vest that'll send a shard of steel and "good intentions" through your aorta.
