Of course it did.

No it didn't, it came from Petersen Mfg Co's trademarked "Vise-Grip" clamps,
that used William Petersen's patent of Jan 5 1923.

Petersen's product was the 'Vise-Grip' locking pliers. The remenents
of his original company and the 'Vise-Grip' name eventually beame part
of Irwin (which is owned by Newell Rubbermaid).
