No. Cobalt 59 does not spontaneously transmute into cobalt 60, except in nuclear reactors. Keep your knives out of nuclear reactors and you’ll be fine.SpyderEdgeForever wrote: ↑Fri Nov 16, 2018 11:39 pmI do not want to sound paranoid or sensational, this is a sincere question. Some time back there was a thread on the forum here about VG10 and other cobalt-containing steel alloys for a "space/astronaut" knife, and it was commented that the naturally-occuring isotope of the cobalt atom, cobalt 59, can tramsmute into cobalt-60, a radioactive isotope that emits gamma rays. As you may well know, gamma rays are the most powerful known radioactive rays, more so than x-rays, and gamma rays are very detrimental to biological life.
Now, I love VG10 stainless steel. It is one of my favorites. And Spyderco crafts excellent knives made with VG10 blades.
I need a "reality check" here: Could our VG10 blades transmute into toxic radioactive knives and slowly poison us, or, not?

Now what happened there was that cobalt 60 was improperly disposed of and contaminated the steel bowls and other items. That is different than transmutation but it raises the same basic issue.
I love my Endura, Delica, and other VG10 knives. Does this mean we have to switch to a non-cobalt steel, like H1, or LC200N?
Don’t know, but the Ball watch company uses tritium gas tubes to light their watches. Radioactive and stay lit all night. Cool. Not particularly dangerous.
