NOS Vintage 1980's Metrinch 12-Point Socket Set Review

In this episode of "Socket Obscura" we take a look at the original 1980's era Metrinch (not MetWrench) sockets.
Are sockets that fit both Metric and Inch fasteners the key to stopping the upcoming alien invasion??
Should the government force "Big Socket" to make these sockets again??
These were widely advertised on TV and in Popular Mechanics magazine, as working on both Metric and Inch fasteners.
These used a unique dual broaching system, where one 6 point broach was for SAE, and the other 6 point broach was for Metric.
To give you a 12 point socket, that would fit on two different size bolts.
We'll test them out to see if they actually do fit on two different sizes.
