Stone working tool having multiple striking edges on reversible-replaceable plates

A hand held stone hammer comprising:

• two detachable, replaceable, rotatable, individually reversible, rectilinear faceplates, each faceplate comprising:
• four striking edges on each of a first and a second opposing side of each faceplate;
• four countersink openings through said faceplate from said first to said second opposing side, each opening being countersunk on each of its opposing sides, said four openings being symmetric about each of three orthogonal planes of each faceplate;
• a weight-bearing head adapted to receive a handle and adapted to receive said faceplates at opposing ends of said head, said head comprising four threaded openings on each of its opposing ends, each threaded opening positioned to align with respective ones of said countersink openings, wherein each faceplate is attached to said head by four threaded fasteners positioned within respective ones of said countersink openings and threaded into respective ones of said threaded openings, wherein:
• a striking edge is selected by at least one of rotating a faceplate by 90 degree increments, reversing a faceplate, replacing a faceplate, and striking with an opposing end of said hammer.
