Really ???? Just asked an honest question.
This is a knife related forum hence my question is focused around knife.
I admit that that was my first thought as well. Someone thought this would be a sly way to turn a bunch of people off of evil MIC knives, by starting them thinking that maybe they could get sick handling them. I don't know what your actual intentions were, but that what it sounded like to me. You should have said "I am curious what, if any safety precautions are being taken by Chinese knife makers". Although it's unlikely that they'd have made any yet, or that we'd know if they had. It's early days, and it's a huge expense to expect them to treat ALL their products just in case one of their workers was carrying the disease. They certainly aren't going to allow them to work when sick. And of course, as already said, this would apply to ALL Chinese products, not knives specifically. I really don't expect the manufacturers to do very much about it. It would be a waste of money.
In any case, the longest time quoted on here for a virus to live outside a host is 28 days, and that's an exceptional case. It usually takes 6 months to a year for a product to leave the factory and reach a consumer, often much longer. They make the knives; they are packaged, put into cases. These cases are stacked into pallets. These pallets are stored in a warehouse, depending on shipping schedules and the shipping backlog they already have (they want to get rid of the older stock first). When it's finally time for that batch to ship, they are packed into shipping containers, then they are loaded onto a ship, which can take days or weeks by itself. Then a trip across the ocean: another two weeks. Then unloading, storing into warehouses. Again the older stock is rotated out first. Depending on how time sensitive it is, the merch can sit for weeks, month, or years before it's finally sent out. It's packed into trucks or trains, set across the country by pallets. Again stored in warehouses, for differing periods of time. Then again, they are taken out, broken into individual lots, sent to stores across the region. Once stocked on the shelf, 6-12 months after leaving the factory, they may sit for a year. Or they go to an online provider, and sit until someone orders them.
Your most likely bet would be if you were ordering directly from a Chinese online seller, or someone like Amazon using a Chinese 3rd party supplier. You order from them, they give the order to the Chinese company, who sends directly to your house. But that's almost never the actual manufacturer, and the item is still usually taken from warehouse stock. Even if you bought from a manufacturing/marketing company that mails direct to your house they would endeavor to sell off old stock first. It's almost inconceivable that an item would roll down a production line, through diseased hands, into packaging, be snatched up and sent by parcel post directly to your house. If you are worried about that small chance then make sure you don't buy directly from Chinese suppliers. Or just disinfect. And watch out for the flu, because that is all over the place and just as dangerous (it just doesn't generate clicks the way an exotic "potential pandemic!" does).
There are plenty of good reasons to avoid knives made in China, but this isn't one of them. You are actually more likely to get sick buying a knife on Ebay from someone in the US.
