Abstract
A string loop tensioning pliers device includes a first member comprising a first handle and a fixed arcuate jaw comprising an upper jaw and a lower jaw. The lower jaw has an arcuate claw end and the upper jaw has a first lateral dowel pin end and three in-line lateral facing beveled prongs. A second member comprises a second handle pivotally connected above the first member and includes a notched end opposite the handle and a second lateral dowel pin configured to join with the middle prong when the pliers are closed. A method for using the disclosed tensioning pliers includes tensioning a string knotted to the bowstring, spreading a loop created on the bowstring and tensioning the created loop by inserting the middle prong joined with the second lateral dowel through the formed loop and squeezing the pliers to separate the middle prong and the second lateral dowel.
