I love the logical thinking and advice. I don't really like the 'you're a dumbass' suggestions

but I guess it comes with ... the Knife Tribe? ;-) And maybe it holds some truth.
After pondering my endeavors for a while, I've come to understand that this is not a fair test for this knife. I'm glad I did it (and I bet some of you are jealous I did it and you daren't do it to your knife
I think I was sort of expecting (or hoping?) it to be less easy to push through the lock, AND I realized that it's hard to come up with a situation in which I will apply such pressure on the knife in a real life situation. I have also found Mini Grips on youtube that had lock failure, people who were very happy with their little Bantam and had carried it around for years, et cetera. And in hindsight, the anatomy of the knife (plastic handles) calls for this flexibility in the system.
If I regard it as a little companion that helps me cut paracord, open boxes and things like that, it's just fine. I changed my ideas and expectations.
I also think that what has triggered me to test the knife (in a bit of a weird fashion I suppose) is to really get to know the anatomy of knives, how to value them and trust them - or not! - how to use them safely. I find it fascinating that this little thing can cut through an apple, but also do harm and wound when used with other intentions, or when making an erroneous judgement or being clumsy. I'm intrigued by this power it holds.
Thanks for all your input!
