Spoke Wrench Patentee: Leon M. Cabana - Buffalo NY Granted:1900-05-29

A distinctive bicycle spoke wrench marketed as the BABY Neverslip. It has an eye on the back side to attach it to a watch fob. It is a half-size version of the Neverslip Nipple Grip. The NEVERSLIP has a distinctive shield image cast in both sides. The design may reflect Spanish-American War era patriotic fervor. As part of a settlement of patent disputes, the Buffalo Specialty Mfg. Co. transferred the "Baby" and "Neverslip" grip patents to the G.W. Cole Co. in 1901.
