I was wondering if patina formed on CPM-M4 (Gayle Bradly) is toxic. Would there be any ill effect on health (adult and especially new born)? Yeah, I do have H-1 for kitchen cutting. Just wondering.
Thanks for the help. :cool:

Why would it be any more dangerous than the patina that has been cultivated on well cared for carbon steel kitchen knives for centuries as a rust preventative? From what I understand, it's an oxide of iron, just not the one we're most use to seeing. It might even have health benefits, in the unlikely event any of it transferred to your food.

Now... I've seen a gun "blued" patina and I would assume that is not safe to eat off of. Does it depend on what you use to patina the blade?
Most of the time for patina I see vinegar and mustard, which are safe to eat.

Wow, those are some pretty old people. Maybe patina extends life but I'm pretty sure if I used a blade with patina to prepare food with I wouldn't last much longer than 250 years. :DRedeye wrote:People have been 'eating patina' for thousands of years! Stainless steel has only been used for cutlery since the beginning of the 20th century, and everybody was using patinated knives before that. You and your family will be fine :)
Actually, I never thought of that. Patina is a form of corrosion though, isn't it?

I believe that because when my son was little he stepped on a rusty nail. I took him to the ER and the doctor was more concerned because he was wearing old sneakers and socks than he was about the rusty nail. More bacteria to worry about is in shoes and socks he said than on a rusty nail.justinl wrote:even rust isn't toxic itself. rusty metal is just naturally associated with unkempt dirty blades. It's the "dirty" part that has the potential to transfer organic pathogens like tetanus and Lordy knows what else.
