I would ask you to add Mitchell Leather to that list.

Family-run business in Milwaukee since the late 60s (when we were the leather capital of the US), hand made, artisanal level. And because they're small production they can source smaller batches of higher-quality leather than the "big boys" can get.

I've got one of their money clip wallets and love it, and my father has had one of their briefcases for the past twenty years and I'll almost certainly inherit it when he dies.

Not a shill, just a happy user of some of their products.
