Pretty sure that’s the MCMO. Checkout this announcement post from YYE a while ago. It has that fade w/blue ul’s as one of the MCMO colors that dropped.
First thing you do is to throw the yo-yo into a garbage disposal. Remove the pipe trap at the bottom of the disposal. Gather All the metal shavings into a waterproof Pelican case.
Secure the seams with 20 layers of invisible tape.
Goggle the location of the hidden Government Metalurgical Laboratory. It isn’t that hard to find. Just pull up a map screen on your phone and look for a half inch circle that has no Business markers.
Drive to the location in an unmarked car. Arrive at high noon or midnight; whichever comes first. Make sure to wear sunglasses a 10 gallon hat and a full length black trench coat, so as not to attract attention.
Do the secret door knock using the top of your head. It gives a more hollow sound on the inside and lets them know you are family.
Pour the yo-yo fragments on the test table. First, they will measure the hardness of your cranium. The Rockwell hardness will prolly be, like 58 or so.
Then, they will test the fragments from the yo-yo. If…. They are less than 58, most likely 6061.
If…. Greater than 58, than prolly 7075. If…… the fragments glow in the dark in a well lit room, better call Jeffrey Pang at Luftverk. He can’t do anything, but he always likes oddly interesting stories.
Easiest way to find out the alloy but you will prolly need a new yo-yo.
Good luck.
PS… or, maybe just take the easy way out and contact One Drop, directly via email and ask them?
