Interesting knife lock test methodology and some "big name" surprising fails .

I don't stab anything....I like slicing tests..where geometry is large..

You're missing out.

Everything has its limit. Common sense says don’t exceed it. YMMV

I think the spine whack thing is a parlor trick, it relies on bouncing the lock open due to rebound of the spring/lock when whacked. That my opinion and no im going to test the theory on ANY of my knives.

I've seen some cheap Italian stiletto style switchblades that had very questionable locks. No way would I want one, even though they are legal to carry here in Massachusetts now.
