ABSTRACT:
A method for producing, per se, individual or multiple enlarged-abrasive-globule-carrying flexible bristle(s), with each abrasive globule being firmly and fixedly, and virtually non-accidentally-removably, attached to, and thereby carried on, a corresponding tip end portion of a corresponding flexible (often nylon plastic) bristle, achieved by successive and intermixed and/or alternating multiple-adhesive-matrix-and-abrasive-particle-applicatory steps, a junction-strength-increasing step, multiple laminating and curing steps; and a multiple, composite form of the above-defined method, comprising a method for producing a flexible abrasive hone by assembling a generally similar plurality of such enlarged-abrasive-globule-carrying flexible bristles and effectively firmly mounting bristle rear end portions with respect to a bristle-holding base in a relatively evenly spaced-apart manner and with the bristle tip end portions and the bristle rear end portions being generally similarly longitudinally-spaced, along bristle lengths, such that each enlarged abrasive globule of the plurality thereof, and all of same, is/are positioned at generally similar bristle-length-spaced forward honing locations in closely-laterally-adjacent-to-each-other, but individual and non-interfering positions, and, thereby, together defining an effective multi-element, common, flexibly-supported honing surface.
