Uh…yeah it’s definitely Nathan that’s to blame 
Completely unrelated but if you need two for an upcoming project, hit me up…usps envelope should only be a couple bucks 
But realistically for a good source of ~constantly stocked US made single form tools at an ok price I’ve read good things about onlinecarbide: THREAD MILLS - SINGLE PITCH - onlinecarbide.com
(~$30 per tool…definitely not import pricing but much more reasonable than the $90+ per tool of the bigger brands)
Oh also nice, especially for folks on the west coast, the carbide tool source guys are back in business. Just a couple of guys in Oregon grinding very reasonably priced high quality carbide tools.
They’ve been a bit unreliable recently because of health issues so I’m not sure it’s a great idea to single source them as a vendor but they’re a great option for smaller outfits:
@nwilson when using steel specific cutting tools just watch out for coatings with aluminum. It’s common for steels but won’t play well if using them to cut aluminum
