  • Welder here. Aluminum oxide inhalation is correlated with an increased risk for alzheimers, not cancer. Hexavalent chromium is a carcinogen, and that comes from heating up stainless steels. So you are actively replacing a relatively non toxic oxide with the potential for an actually toxic carcinogenic gaseous metal, assuming your pocket knife is some sort of stainless steel (statistically very likely).

    This has always struck me as a dumb argument. Before “intellectual property” innovation was just technological advancement. Patenting is just enabling punishment against actual innovators. I am a welder. I make things. If I set out to make a stove, I don’t give a shit who patented what fuel distribution system or air intake methodology, I’m gonna make a damn stove. The entire concept of being able to exclusively “own” a design or concept is reductive to human learning as a whole.











  • Maybe I’m biased because I’m a welder, but it always made more sense to me that electricity flows from the negative. Like , if the positive moved, wouldn’t you change the element of the wire after a while? It also helps that you can tell the difference if an arc is positive or negative relative to the stinger depending on how the metal reacts, at least to a welder. I know that doesn’t make any sense at all but it does to another welder lol
