Abstract

Methods, systems, and devices for a knife with a shearing arm are described. In some instances, a knife may include at least one integrated shearing arm. For example, a knife may include a retractable blade that may be used to perform certain types of tasks such as cutting rope, cutting bate, killing a catch, and the like. Further, the knife may include a cutting shear having a retractable arm for performing different types of operations, such as cutting fishing line. The cutting shear may be integrated into the handle of the knife such that the knife's liner includes a blade (e.g., a first blade of a shear) and the arm includes a second blade (e.g., a second blade of the shear). The arm may be spring loaded or otherwise configured to rotate toward and away from the body of the knife in a shearing motion.
