A crimping tool for applying a deformable crimp seal onto overlapping layers of strap material includes a head and pairs of jaws disposed in the tool head and operably mounted thereto. Each pair includes opposingly oriented jaw elements. A shear extends between and is operably connected to the jaw elements. The jaw elements have an inwardly oriented crimping portion with a tip having a tapered portion terminating at a free end. A pair of handles are operably connected to the jaw elements and to one another. A side plate is operably connected to the jaw elements and shears and includes a centrally disposed slotted opening. When the tool is in a closed position the jaw elements of each pair align with one another and the free ends of the opposingly oriented jaw element tips overlap in a direction transverse to the jaw elements.
