The hammer surface is located on the wrench head rearward of the adjusting mechanism. In addition, the wrench handle is adapted to function as a screwdriver, measuring ruler, wire stripper, and T-handle. The handle and base of the wrench head form a square face. Inch and metric measuring scales are provided on the wrench jaws with auxiliary Vernier scales for accurate measurement. ## Claims ### Claim 1 A wrench comprising: (a) a wrench head having a fixed first jaw, a crown and a base wherein said wrench head is provided with a first major surface with an inch measuring scale for indicating the distance between the first and second jaws, and said wrench head is provided with an opposed second major surface with a metric measuring scale for indicating the distance between the first and second jaws; (b) a second jaw slideably mounted in the wrench head wherein said second jaw is provided with a first major surface with an auxiliary Vernier scale to allow more accurate reading of the distance between the first and second jaws, and said second jaw is provided with an opposed second major surface with an auxiliary Vernier scale to allow more accurate reading of the distance between the first and second jaws; (c) an adjusting means for varying the distance between said first jaw and said second jaw; (d) a hammer face positioned between the crown and the base of the wrench head; and (e) a handle with a proximate end mounted to the base of the wrench head, and an opposite distal end. ### Claim 2 A wrench comprising: (a) a wrench head having a fixed first jaw, a crown and a base; (b) a second jaw slideably mounted in the wrench head; (c) an adjusting means for varying the distance between said first jaw and said second jaw; (d) a hammer face positioned between the crown and the base of the wrench head; and (e) a handle with a proximate end mounted to the base of the wrench head, and an opposite distal end, wherein the base of the wrench head is substantially planar and the handle has at least one straight edge perpendicular to the base of the wrench head. ### Claim 3 (depends on 2) A wrench according to claim 2 wherein: wherein the proximate end of the handle is provided with a first major surface having an angle measuring scale; and the base of the wrench head has a projecting shoe which can be moved arcuately across the angle measuring scale. ### Claim 4 A wrench comprising: (a) a wrench head having a fixed first jaw, a crown, a top edge and a base; (b) a second jaw slideably mounted in the wrench head; (c) an adjusting means for varying the distance between said first jaw and said second jaw; (d) a hammer face positioned between the crown and the base of the wrench head wherein the hammer face is substantially flush with the top edge of the wrench head; and (e) a handle with a proximate end mounted to the base of the wrench head, and an opposite distal end. ### Claim 5 (depends on 4) A wrench according to claim 4 wherein said wrench head is provided with a first major surface with an inch measuring scale for indicating the distance between the first and second jaws; and said wrench head is provided with an opposed second major surface with a metric measuring scale for indicating the distance between the first and second jaws. ### Claim 6 (depends on 4) A wrench according to claim 4 wherein the handle is provided with a first major surface with an inch measuring scale; and the handle is provided with an opposed second major surface with a metric measuring scale. ### Claim 7 (depends on 4) A wrench according to claim 4 wherein the handle contains at least one square aperature. ### Claim 8 (depends on 4) A wrench according to claim 4 wherein the handle has a peripheral notch adapted to stripping insulation from wire. ### Claim 9 (depends on 4) A wrench according to claim 4 further comprising an insulating grip having an opening conforming substantially to the shape of the handle, and permitting the handle to be inserted into said opening and frictionally secured therein. ### Claim 10 (depends on 4) A wrench according to claim 4 wherein the distal end of the handle further comprises a screwdriver.
