Description: |
"Tweak" on the Stillson type pipe wrench includes the location and shape of the springs between the handle and frame for the adjusting nut. The pivot point between the handle and frame is a pair of lugs on the handle, and corresponding grooves in the frame so that the parts can be assembled without the use of a rivet or pivot pin. |
