Abstract: An angle clamping tool is provided having a handle including a lockable clamping mechanism operably connected to two jaw arms. Each jaw arm includes an end portion and a medial portion. Secured to the end portion of each jaw arm is a clamping jaw comprising a pair of two elongate clamp members. The clamp members are adjustable to form a selected angular relationship with respect to each other, depending on the types of materials being secured together and the uses for such materials. Once a selected angle is obtained, means are provided for locking the clamp members in such angle during use. The jaw arms in the invention are designed so that, when the handle portion is gripped, the clamping jaws move inwardly toward each other so as to meet and engage work pieces therebetween. The jaw arms are further designed so that when the clamping jaws meet, the medial portions of the jaw arms are sufficiently spaced from each other to permit passage of the clamped work pieces therebetween.
