Abstract
A razor blade member has a first planar portion and a second planar portion connected to the first planar portion by a transition bend region. The longitudinal edge of the first planar portion remote from the transition region is sharpened to a cutting edge. The blade member also includes stress balancing deformation along the longitudinal length of the planar portions and adjacent the transition region. The bow of the second planar portion is less than 0.05 millimeter per centimeter length of blade member.
Claims20
A razor blade member that has a first planar portion and a second planar portion, said second planar portion being angularly offset from said first planar portion and connected to said first planar portion by a transition region, the longitudinal edge of said first planar portion remote from said transition region being a cutting edge, and stress balancing deformation along the longitudinal length of said planar portions and adjacent said transition region.
A razor blade assembly comprising a body member;
- a blade member disposed in said body member, said blade member having a first planar portion and a second planar portion, said second planar portion being angularly offset from said first planar portion and connected to said first planar portion by a transition bend region, the longitudinal edge of said first planar portion remote from said transition region being a cutting edge, and stress balancing deformation along the longitudinal length of said planar portions and adjacent said transition region;
- structure in said body member for supporting said blade member for movement relative to said body member in response to forces encountered during shaving in a direction along the plane of the second planar portion;
- and biasing structure in said body member for urging said cutting edge of said blade member into a reference position from which it is moved in response to forces encountered during shaving.
