1. A force modulation system for a drill bit, comprising:
a cutter being comprised of a cutter body having a cutting end, and a cutting surface made integral with said cutter body at said cutting end;
a holder being comprised of a holder body having an anchor end, a holding end opposite said anchor end, holder sides between said anchor end and said holding end, and a holder cavity at said holding end, said cutter body being in removable slide fit engagement with said holder cavity;
a holder retention means positioned on at least one holder side so as to exert a holder retention force in a first direction of said holder;
a first force member positioned against said holder so as to exert a first force in a second direction of said holder, said second direction being angled offset to said first direction,
wherein said first force member is comprised of a first wire woven material with a first elasticity; and
a second force member positioned against said holder so as to exert a second force in said first direction of said holder,
wherein said second force member is comprised of a second wire woven material with a second elasticity,
wherein first force member is made integral with said second force member, said first wire woven material being compatible with and bonded to said second wire woven material,
wherein said first wire woven material is identical to said second wire woven material, said first wire woven material and said second wire woven material forming a unitary body, and
wherein said unitary body is comprised of a first portion, a second portion, and a hinge portion between said first portion and said second portion, said first force member being comprised of said first portion, said second force member being comprised of said second portion.
