Superstar is a company from the UK that up to this point has has focused on consumer direct sales for a number of different parts. When it came time to introduce their new I/O narrow wide chain rings and Trident bashguard however, the company wanted to cut down on lead times from their Asian suppliers. That meant bringing production in house. After making a substantial investment in machinery, the first run of UK made parts are starting to roll off the line in typical Superstar fashion.
Using a narro-wide alternating tooth pattern like many of the new rings popping up, the I/O chainring also has what they call precision machined debris gullies to help evacuate the UK mud (or any mud/debris). Machined from 7075 T6 aluminum on their own machines, the rings are compatible with 9, 10, and 11 speed chains and are offered in 32, 34, and 36t rings with 104 BCD in a number of colors.

In order to program their CNC machines, Superstar has been working with Delcam who supplies their CAM software which works inside of Solidworks. Delcam put together this video that gives you a look inside the Superstar manufacturing process.
In addition to the I/O chainrings, Superstar is also machining their own aluminum bash guards with the Trident. Again machined from 7075 aluminum, the 4 bolt, 104 BCD guards are machined to remove as much weight as possible while still protecting the ring under hard impacts. Sold as 34t compatible with a chainguide, the company says they are compatible with up to a 36t chainring without a guide.
You can pick up the Trident for £22.99, and the I/O ring for £25.99, here.
