The OmTara Crimping Pliers make the crimping process easier, more efficient, and more fool proof. This version has two crimping notches for crimps 1-4mm diameter. The smaller notch is for use with 1-2mm crimps. The larger notch is for 3-4mm size crimps. OmTara Crimping Pliers support the artist's creative process rather than inhibit it. An easy one step process to achieve a secure crimp which can then be left as is, folded or flattened, or covered with a crimp cover.
