1. A razor handle comprising:
a main body;
a pivoting head pivotally coupled with said main body about a first axis of rotation, the pivoting head being configured to receive a razor cartridge;
a benefit delivery member, extending from said main body to said pivoting head, said benefit delivery member providing a first biasing torque on said pivoting head to affect an angular deflection about said first axis of rotation of said pivoting head relative to said main body;
a spring member extending from said main body to a said pivoting head, said spring member applying a second biasing torque to affect an angular deflection about said first axis of rotation of said pivoting head relative to said main body; and
wherein a ratio of (i) a sum of said first and second biasing torques divided by said angular deflection in radians of said pivoting head to (ii) said second biasing torque divided by said angular deflection in radians of said pivoting head is greater than 2:1 and said benefit delivery member is compressed when installed.
