Claim 11

Dependent Claim 100 words

A tooling assembly as recited in claim 5, wherein each slot of the stationary shear comb opens into a longitudinal edge thereof, these slots being defined by shear finger guide ribs extending transversely of the length of the stationary shear comb and projecting normally thereof, towards the pivotable shear comb when that comb is in its closed position, the stationary shear comb defining a connector receiving recess extending lengthwise of the tool body, proximate to said guide ribs, a connector locating block being slidable along the connector receiving recess and being securable in desired positions lengthwise of the tool body.
