So, i collect folding knives for fun. Sort of like guitars, I have some high-end ones, some quirky ones... I'm working on my laptop when she asks me if she can borrow one of my knives "real quick" for something. I say sure, and continue working. I hear her come in and out of the house several times over the course of the next hour and a half. My curiosity gets the better of me after a while and go outside to see what he's doing... Next to a tree is my pocket knife collection thrown about on the ground as she is sawing away at a tree branch the size of my neck. Yes, "sawing" with a plain edge knife, not "chopping" or "hacking", she was pushing them into the branch with all her weight expecting them slice it in half like Excalibur. No, she didn't even try with any of the ones with serrations, she started with what she thought was my sharpest knife (read: most expensive) and worked her way down... pushing as hard as she could. Then when they stopped being "effective", she got the next one. "Your knives aren't very sharp". "it's the wrong tool for the job, you need a saw or an axe" "There aren't any around, you sound annoyed with me..." I went inside and got her a serrated kitchen knife so she could continue (yes, I know where the axe is), then checked if my M4 Benchmade could still cleanly slice paper... nope. Cheaper knives had clear rolls.. I mean, I can't imagine what she was thinking doing this for an hour and half.. that's some edge retention test.
