Jorgensen hand screws are now apparently made in China, and the quality has dropped accordingly.  They are no longer any better than the shoddy hand screws you can buy at China Freight or R*ckler.  The threading on the new ones is not a square thread, the handles are much cheaper now, and the rivets holding the handles on are chincy and break free.  Very lame.  Congratulations if you receive a genuine made-in-USA version, but don't count on it.
