=> food safety of blade steels (blued, etched etc)?

I've often wondered why blueing is considered unsafe for food prep. After all, blueing is just rust and rust is patina. But there are different types of blueing. Hot caustic blue is a far different process than cold rust blueing. Truthfully, I don't think I would have a problem using a blued knife for food prep. The teflon coming off of the non stick pan is harmful, and few people avoid those.
 
Cold bluing could be considered an issue if the cold bluing solution (selenium-based) is not completely washed off. But if done properly you only have an oxide layer. Food exposed to a simple carbon steel patina is no different from food exposed to cast iron cookware.

Within reason, genetically modified foods are perfectly safe. Those contrails are actually water vapor (like the exhaust that comes out of cars when it is cold outside) that condenses and freezes in the air because it is so cold that high up in the atmosphere. Planes don't burn weird chemicals, just very specific formulations of kerosene (a type of hydrocarbon similar to diesel). Working in a nuclear reactor isn't that bad radiation-wise. Did you know that the potassium in your body bombards you with more radiation that working in a nuclear power plant?

In response to the OP, I try to only use uncoated blades for food. I don't know much about the regulations for knife blade coating manufacturers to trust that they have had stringent enough controls on chemical safety. Is this probably worrying too much? Yes, especially since there are so many other chemical risk factors that I am willing to overlook (e.g. paint and adhesives) on a daily basis that is probably wouldn't matter much.

Those are not water vapors #1. I mean think about it really think about it. Most engines upon the initial startup will give off a little bit of fumes. So why is an airplane thats been in flight for such a long time periodically start and stop the vapor trail/Chem trail??? furthermore pictures have been revealed showing the actual chemical tanks that are inside the airplane that are used to create these trails. Also there's been many cases of people who have found out what their planes are carrying and what they're doing. They quit and have gone public with it.

and you saying that GMO food is safe is complete idiocy. I'm not even going to comment further on it. Just do your research and realize that anyone that's conducted the test longer than 4 months has shown an increase in 80 percent of tumors and organ failure that lead to death in mice.

I'm not sure that I should even dignify this with a response...

I've been around airplanes my entire life. My Dad is a pilot. Several of my cousins, friends, and extended family are pilots or airplane/helicopter mechanics. Are you really telling me that there is a conspiracy to put "chemicals" in the air that reaches across continents (e.g. Dassault, Boeing, Airbus, Bombadier, Honda, GE, Pratt & Whitney, etc.)? I've cleaned - by hand - the inside and outside of turbofan engines as a summer job.

Perhaps you should look into combustion, thermoclines, and atmospheric temperature and pressures. Here's a nice graph:

You do realize that people have been genetically modifying food for a very long time? How do you think that apples, corn, rice, and pretty much every agricultural product got so big and produces so much fruit?

Have you looked into the massive benefits that Golden Rice could provide? The massive number of lives it could save?

http://en.wikipedia.org/wiki/Golden_rice

Obviously there could be very real problems if GMO crops were not tested rigorously enough, or how the biosynthesis of the various biochemical products could produce undesirable products in hundreds of biochemical pathways. The benefits of GMO shouldn't be foregone without taking a very real and very serious look at the benefits while weighing the costs (not just the risks, but also the billions of dollars that could be spent elsewhere).

My apologies to the OP. This thread has strayed from its original purpose and I'm not entirely blameless.
 
All I have to say is that scientists once considered the earth to be flat. Scientist once considered earth to be the center of the universe and that all the planets revolve around the earth. Scientists once believed the sun rotated around the Earth. Then Scientists believed the Sun was the center of our universe. Now Scientists realize we are not the center of our galaxy let alone the universe.

Take what you are told as scientific truth with a grain of salt and think for yourself. Not all scientists agree with one another and not everyone loved Jesus when he was here.
 
The majority of people in history, at least from the time of the ancient Greeks, had a fair idea what the size and shape of the Earth was. Geocentricism was a model supported by the available evidence, and heliocentricism didn't really get the kinks out until the nineteenth century. Your other comments are just nuts.

There's no point in being so open minded your brains fall out.
 
Some of you guys are too trusting of a lot of things. Asbestos was deemed safe for the longest time until it wasn't. This same example could be said of so many things in so many different fields and applications.

I'm not talking about commercial airlines. I see planes in the sky that leave no trails whatsoever. I also see planes start and stop these trails.

If GMOs were so good for people why have so many countries banned them?? Furthermore, I personally know scientists that have tested some of these GMOs and informed me of how horrible they are for us. No I'm not going to name them.

Believe whatever you want. That is your right.

Believe me my brain is not falling out in any means.
I'm studying biomedical engineering, Biomechanical Engineering, and bioelectrical engineering. Focusing on design and development of artificial and organic organ and limb replacement. Also focusing on prolonging life indefinitely. I'm not a tin hat wearer as you may want to call/label me. You have your beliefs and I have mine. Except I have enough respect to not name call or ridicule you for not sharing my beliefs. I actually prefer people to not agree with me all the time. Gregor Mendel, Thomas Edison, Nikola Tesla, long list more have been deemed crazy insane nut cases. Yet who changes our world in profound ways? Those who conform with the majority of society don't make changes. Those who think outside the box, those who go against the norm and put themselves out there to be ridiculed make the changes. We should all try to think outside the norm, question what we are told is absolute, and wonder what if.

Done arguing over it. :)

To the OP sorry for the stray off topic but the body takes care of itself for the most part. If anything damages the body it's mostly things that are exposed to the body overtime numerous times. So if you use the same knife over and over and over again on all your food for years and there's something in that blade leaching out and into the food then yes it could affect your health. my point was to say that there's many other things that will probably affect your health more rapidly than a steel blade that you use to cut your food with.
 
I only use coated stainless blades if I use any to prepare food

I wouldnt want the metro wussiness that comes with using stainless steel to leech into my food and affect my masculinity .

( joking , joking .. well mostly )
 
There is way too much off-topic conversation going on in this thread. This thread is in the General KNIFE discussion forum so post accordingly.
 
Bluing is basically a controlled corrosion taken to protect the base metal from uncontrolled corrosion. If chemical components like mustard or onion are used you control the "bluing" by how long you let the process continue.
