The focus of the patent is the manufacturing process to produce the handle of a conventional pocket wrench solely by forging. In this patent, the longitudinal slot is formed by two slots on opposite sides of the handle, each extending more than half the length of the handle. The overlapping area of the two slots forms the opening for the adjusting nut.

SPEIRS pocket wrenches marked with this patent date, but with both sides of the handle enclosed, are also known. Another example marked "H.B. & Co. New York / Pat'd Sept. 8 1891" suggests Speirs produced the wrench for cycle manufacturers like Hulbert Brothers.
