Abstract
A shaving system comprises a leading blade member having a cutting edge and a following blade member having a cutting edge. The cutting edges are supported in spaced parallel relation to one another by structure which extends along substantially the entire lengths of the leading and following blade members and a guard structure is disposed forwardly of the leading cutting edge. The guard structure is disposed relative to the leading cutting edge to define a leading edge tangent angle in the range of 20 DEG -32 DEG and a span (SL) in the range of 0.030-0.080 inch, the following cutting edge is rearwardly offset from the leading cutting edge to define a span (SF) in the range of 0.030-0.080 inch, and each cutting edge has an exposure in the range of from -0.002 inch to +0.004 inch.
