Yesterday, I washed two carrots with water and then went on to peel them with my coated(black) CQC-7BW (year of manufacture 2009).
The oddest thing happened. As soon as I finished peeling the carrots I noticed discoloration on the black coating of the blade. The discoloration was greenish with a metal tint. It shows on both sides of the blade and is patterned as if wiped on there with a rag or something.
Obviously it's from peeling the carrots as it appeared instantly after the peeling. The discoloration is visible in most lighting conditions but not very strong at all.
I washed the blade with hot water and wiped it dry after peeling, perhaps 3 minutes later and the discoloration remained. Maybe I'll try a rough sponge later and some soap. But maybe it's permanent. Oh the horror
Sooo....Is this someone else has experienced with CQC series coating, with other veggies/fruits? Anyone know what exactly caused this?
I've never seen carrot acids cause this kind of discoloration. It seems the acids reacted with the coating.
FAQ:
Yes, Im certain my knife is from Emerson.
No, the edge didn't chip or deform from peeling.
No, it is not dull after peeling 2 carrots.
No, the carrots were not nuclear/uranium treated.
Yes, They tasted fine.
Yes, Im still alive and feeling fine.
No, I have not developed a need to eat human brain. Yet
