I just bought this little cheap folder that has mircata handle scales and I put it down to scratch my nose I noticed a strange metallic smell on the hand that I was holding the knife in. I picked up the knife and took a sniff, it's a really weird smell and it rubs off on my hands if I'm holding it for awhile. I took it over to the sink and gave it the once over with some dishwashing soap and a brush, rinsed it in really hot water and it still smells bad. Anyone have any clues as to what could cause this.
