as an example of doing it the right way by a knife company: a while back, the US foundry producing 1095 cro-van steel shut down. That's the primary steel for most of KaBar's knives that are actually produced in the USA. As a result, they had to start ordering their steel from a German supplier. Due to a tightening of the laws concerning "USA made", they had to remove the USA marking off their knives in 2019 or 2020, because foreign steel was the main component of their product and NO amount of processes done in country was enough for them to label the knives as a USA product under those laws.
