There was a huge amount of Manufacturing in the Mohawk Valley all along the Erie Canal; if it was made of metal and or wood, it was made there.
Clearly New York was a major producer to the War Effort in WWII, but that's history and one not likely to repeat.
We drove out to Sherrill Manufacturing a couple of years ago.. "It is the only flatware (metal cutlery and tableware) maker that manufactures its products in the United States of America." Oneida LTD roots.
I've got a 16" Oneida Limited Bayonet for my Garand that my son found in a repo'ed house he was helping to clear out.
I've been in the Oneida area most of my life and can remember the traffic coming out of Sherrill when the 3 o'clock whistle would blow at Oneida Limited. They had their own skeet shooting range set up behind the plant. I would go watch them shoot as a kid.
