a razor handle elongated body,

wherein the razor handle elongated body includes a back end opposite a docking end;

a central pushrod mounted in the docking end of the razor handle elongated body,

wherein the central pushrod is generally double T-shaped with two shorter bars perpendicular to a longer bar, the longer bar of the generally double T-shaped central pushrod aligning with the razor handle elongated body and slidably mounted into the docking end;

wherein a first bar of the central pushrod shorter bars, perpendicular to the longer bar, is configured outside the docking end and a second bar of the central pushrod shorter bars is configured inside the docking end;

one central hook arm pivotally mounted to the razor handle body at the docking end, within and proximal to the generally double T-shaped central pushrod,

wherein the central hook arm includes a pivot end and a hook end, the hook end including a hook;

a central hook arm axis about which the central hook arm is configured to pivot relative to the elongated razor handle body.

2. The razor system of claim 1 wherein the central pushrod is spring mounted in the razor handle elongated body.

3. The razor system of claim 1 wherein the central hook arm is flexible.

4. The razor system of claim 1 wherein the razor handle includes a button mounted at the docking end that actuates the pivot of the central hook arm.

8. The razor system of claim 7 wherein the cartridge docking portion includes a gap adjacent to the ramp and tab, in which the central hook arm is configured to pivot into the gap, thereby releasing the ramp and tab.

9. The razor system of claim 7 wherein the central ramp and tab includes a fulcrum point at which the central hook arm mates, and about which a force would be imparted on the cartridge when in use,
