Hi everyone!
I am currently creating a multitool similar to the Gerber Shard from an old wrench, which I suspect to be a chrome-vanadium steel. The tool features a spoon, a short prybar, bottle opener, a sharpened edge and a flathead screwdriver. Steels with chromium seem to be food-safe from what I found out online, but how about the added vanadium? The oxides at least are apparently somewhat toxic.
Not knowing this, I have finished an earlier version of it a while ago from the same steel (simply the other side of the wrench), which did indeed give the food a somewhat metallic-biting aftertaste. Is this simply because I just tasted untreated metal or might this be a very light form of poisoning?
Are there any common steel additives that are known to be poisonous or at least not really food-safe?
Thanks in advance!
