Claim 2
Dependent Claim 132 words
A shaving system comprising a handle and a blade assembly, the handle comprising first and second connecting means extending from an end thereof, said first handle connecting means being disposed within said second handle connecting means, the blade assembly comprising a first body portion having thereon a first blade assembly connecting means and a second body portion having thereon a second blade assembly connecting means, the first blade assembly connecting means being pivotally connected to the first handle connecting means, and the second blade assembly connecting means being fixedly connected to the second handle connecting means, said blade assembly first body portion being pivotally joined to said blade assembly second body portion, said second handle connecting means being movable in directions transverse to the axis of a grip portion of said handle.
Claim 3
Dependent Claim 130 words
A shaving system comprising a handle and a blade assembly, the handle comprising a grip portion, a neck portion attached to said grip portion, a first handle connecting means extending from said grip portion and disposed in said neck portion, and a second handle connecting means extending from said neck portion, the blade assembly comprising a body portion having blade means permanently fixed therein, a first blade assembly connecting means disposed on said body portion and engaged with said first handle connecting means to form a pivotal connection therebetween, and a second blade assembly connecting means disposed on said body portion and fixedly interconnected with said second handle connecting means, said second handle connecting means being movable in directions transverse to the axis of said grip portion of said handle.
Claim 4
Dependent Claim 130 words
A shaving system comprising a handle and a blade assembly, the handle comprising a grip portion, a neck portion attached to said grip portion, a first handle connecting means extending from said grip portion and disposed in said neck portion, and a second handle connecting means extending from said neck portion, the blade assembly comprising a body portion having blade means permanently fixed therein, a first blade assembly connecting means disposed on said body portion and engaged with said first handle connecting means to form a pivotal connection therebetween, and a second blade assembly connecting means disposed on said body portion and fixedly interconnected with said second handle connecting means, said second handle connecting means being movable in directions transverse to the axis of said grip portion of said handle.
Claim 5
Dependent Claim 61 words
The shaving system in accordance with claim 2 in which said first blade assembly connecting means is disposed on a first portion of said blade assembly body portion and said second blade assembly connecting means is disposed on a second portion of said blade assembly body portion, said first and second blade assembly body portions being pivotally joined to each other.
Claim 6
Dependent Claim 36 words
