Leatherman plier heads are made in Mexico. Lock releases, bit drivers, and phillips screwdrivers are being MIM'd in India. And we've got reports that many of the SOG parts are being made in Taiwan.
I think it is fairly common these days to obtain components from wherever in the world it makes the most sense to.
