Abstract: A tensional line release device with an adjustable, 360 degrees rotatable pull handle permitting smooth, steady release by a single finger trigger squeeze of a tensional line such as an archer bowstring allowing the maintenance of a stabilized aim. The device is composed of a tensional string retention chamber containing two contiguous, line impinging spheres, mounted in an inner journal, which are held together in an impinging position by inward pressure applied on the diametrically opposite points of the spheres by an external journal of the mechanism. Activation of the trigger mechanism results in movement of the external yoke decreasing the inward pressure on the two spheres so that impinging pressure contact between the two contiguous spheres is instantaneously overcome by the tension on the line causing it to slip between the spheres in a smooth release in a forward direction with no imposed horizontal oscillation or vertical bind.
