摘要： A cutting tool including a first handle, a second handle, a first head portion, and a second head portion. A force transfer mechanism interconnects the first handle, the second handle, the first head portion, and the second head portion. The force transfer mechanism includes a plurality of flexible links configured to resiliently deform and move the first head portion toward the second head portion in response to movement of the first handle toward the second handle. The first and second handle portions and the first and second head portions are integrally formed together with the force transfer mechanism as a single monolithic structure.
