Cobalt is deadly !

I guess the only safe thing to do is put it all in one place and nuke it. :D

Nah, I don't need ALL of my INFI to be sharp on the top... just a few here and there need to be nuked. ;)

Bahhhaaaaa I about fell off my stool when I saw that. Toxic they say?! Well I guess putting all that INFI grinder dust on my eggs every morning may not have been the best idea. Here I was trying to get tough!

I did. It was funny. The 90's were the time of cobalt. Aside from Busse, Boye's Dendritic Cobalt blades were very popular(google it, may find interesting stuff). Then of course Stellite and Talonite. The custom knife maker Kit Carson RIP was the king of stellite. In the late 90's he made me a giant U2 out of Stellite6K. Both Stellite and Talonite were cobalt alloys that were mostly made up of Cobalt and Chromium. Crazy stuff

Cobalt and cobalt compounds that release cobalt ions in vivo

Cobalt and cobalt compounds that release cobalt ions in vivo are being listed as reasonably anticipated to be a human carcinogen. The listing for cobalt includes different types of cobalt compounds that release ions into the body. It does not include vitamin B-12, because cobalt in this essential nutrient is bound to protein and does not release cobalt ions. Cobalt is a naturally occurring element used to make metal alloys and other metal compounds, such as military and industrial equipment, and rechargeable batteries. The highest exposure occurs in the workplace and from failed surgical implants. The listing for this metal and its compounds is based largely on studies in experimental animals.

This does not elaborate on what metal releases cobalt ions into the body, or how that would happen, and it is an educated guess not a proven risk.

I think it was mostly a joke on me, lol. But you are correct, "in vivo" means it has to be released in a soluble form into the living organism. That would never happen in a cobalt based alloy.

On the other hand I love my cobalt based knives because they're so easy to find in the dark. They're the ones that are glowing :p
 
If that alloy where to encounter fruits and vegetables could any of the various compounds in those assist in the release of cobalt ions which then end up in food?

I guess if you had a pure cobalt alloy or even say an 80% cobalt alloy, maybe. Most Cobalt alloys are around 50-60% cobalt. I seriously doubt that it would be an issue. Certainly not in most cobalt steels like N690 or old INFI which had only 1%. Modern INFI (same as modded INFI) has no cobalt, so no worries.
 
But I jest. COBALT IS TOXIC, in fact so toxic that it makes you do this to knives:

It's true. Cobalt made me throw my Battle Mistresses, albeit without much finesse ... or accuracy. Squirrels vacated properties for miles.:)
