Wow, that's some hard work. I'm sure the guys (admins) who work with page content and editing and all can use this somewhere (I'm only an grammatical editor). I'll make sure they see this if they don't themselves. Nice Job! ;3
Try this test again now that the Full Release is out and knife durability has been removed as well as the Hardened [Diamond] Blade removed. Also Subnautica Wiki states that the Heat Blade does less damage than the stanfard Survival Knife.
