Ok that comment was a little out there, but I know for a fact the new production 91A-D tap wrenches, and also the no. 174 tap wrench (which is similar but very small), do not say USA on them. Last time I checked their website was good about labeling COO, and it said USA. I can't think of a rational reason to drop it off the tool. Other tools of theirs have lost the USA marking as well, notably steel rules. This change roughly coincides with starrett growing as a "global" brand. Maybe im paranoid, or connecting dots that aren't there.
Which brings me back to, I prefer the older ones like Ryan pictured. The older ones tend to be smoother, and not just from use.
