Abstract: A vice for a fishhook including a cam, a main body, a pair of jaws defining a chuck at the front ends thereof, an operating lever fixed integrally with a cam, and an adjusting screw threadedly engaged with the main body and having a forward end in abutment with the cam for adjusting the force provided by the jaws on a fishhook engaged by the vice. Each jaw has a tapered portion, and the jaws are positioned opposite one another to define a space therebetween at rear ends thereof. The cam and a portion of the main body are received in the space. The cam and operating lever are rotatable around a shaft which passes through the jaws and the cam. A spring is provided between the jaws and the main body for urging the adjusting screw into abutment with the cam. Cam surfaces formed integrally with the main body are provided for varying the distance between the abutting tapered surfaces of the chuck formed at the front end of the pair of jaws.
