Craftsman double ended 3/8-1/2" drive adapter. Push the drive square in one end of the sleeve, and it's female 1/2 on one end and male 3/8 on the other. Push the sleeve the other way and its male 1/2 on one end and female 3/8 on the other. Kinda bisexual, ain't it? Also have them in 1/4 x 3/8.

I just wore out a Leatherman Wave, and bought a new one.
