Have we talk about King Tutanchamons knife? 3350 year old - made of iron from a meteorit - during the copper age

So, for 3350 years ago King Tut used this knife - before iron was invented... If he uses iron from meteorits - other people can have done the same thing, perhaps. Never say never....
Meteorits can have been used as hammers and other tools, small pieces perhaps was used to make up fire...
Any way, it is a very nice knife, or dagger, nice design - and I so not think that this is the first iron knife they made when I see the design...
