I've been giving this thread some consideration because it does raise some issues we should be aware of. And that is the toxicity properties of certain metals. With our new Spyder Brother "LARRIN" this would be a good question to pick his brain with. Because with his obvious deep knowledge on metallurgy I bet he could set up a chart of metals that have potential toxic properties in them>> even if they are very minor in toxicity it's still something to be aware of especially when working with food.
Because for decades the dental industry had tried to tell us that there was no danger nor was there any toxic properties in the older "silver/mercury amalgam filings that literally millions of people had dentists put in their tooth cavities before these newer ceramic and synthetic materials made it obsolete. Yeah I most definitely think we were lied to big time on that one issue especially and we have no way of knowing what kinds of cancer and other health problems that might have resulted as well as brain disorders from those older silver/mercury amalgam tooth filings. Because mercury I know for a fact can and does create brain function problems. And over the years ( 1940s to the 1990s) we had a literal explosion of mental/brain afflictions like "ADD" and "ADHD" as well as several other behavior disorders being almost epidemic in the USA for those decades to me is not a coincidence.
I doubt if metal toxicity is much of a factor that is directly a concern in knife blades per se >> but it's not a bad idea to be aware of what is potentially toxic or hazardous IMO.
Have a care about conflating correlation with causation.
Is the increase in ADD and ADHD diagnosis due to some external factor (Like filling metal leachate) or is it down to better (and broader) understanding of how to diagnose such disorders and detection rates?
Over the same period, there has been a measurable reduction in inner city violence in the West- several studies are suggesting this is linked to the banning of lead in fuel. There were studies that showed kids exposed to lead had higher aggression rates.....or could it be due to the build of mercury from fillings?
Without some really carefully done double-blind trials, it would be difficult to separate the many causes that drive an observed change
Especially I can recall being a kid in the 80s and there was no concept of ADD or ADHD in UK education.....There were 'naughty kids' and 'remedial kids' and then everyone else. 'Naughty kids' got put into the slow lane with the remedial kids.
Fun Example: You can plot a fair clear correlation between:
1. the Divorce Rate in Maine vs the average per capita consumption of Margarine
2. The number of Nicholas Cage movies released vs the number of accidental pool drownings per annum

I'd also point out that amalgam fillings didn't get replaced due to material superiority of the newer materials or safety concerns- but they are broadly out of favour in the US due to their aesthetic appearance. That's not the case globally.
I have recently had a replacement filling in the UK of metal amalagam because the ceramic one failed
I am not worried about the minute mercury content making me measureably odder as my life goes on
Warhammer 40000 is- basically- Lord Of The Rings on a cocktail of every drug known to man and genuine lunar dust, stuck in a blender with Alien, Mechwarrior, Dune, Starship Troopers, Fahrenheit 451 and Star Wars, bathed in blood, turned up to eleventy billion, set on fire, and catapulted off into space screaming "WAAAGH!" and waving a chainsaw sword- without the happy ending.
