Appeal No. 2004-0119
Application 08/644,170
Appellants’ invention is directed to a hand operated,

1. A pliers-type crimping tool for blasting caps,

single jaw closing operation, said crimping tool composed of
aluminum for providing non-sparking and non-magnetic properties,
and wherein the outer surfaces of the aluminum are provided with
a dense anodic coating to enhance wear properties, and wherein
outer surfaces of the aluminum that are susceptible to wear are
provided with an anodic coating having a thickness of at least
0.001 inch.
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
