Dependent Claim
123 words
A shaving system comprising a handle and a blade assembly, the handle comprising a grip portion, a neck portion extending from said grip portion, a first handle connecting means extending from a free end of said neck portion, and a second handle connecting means extending from said free end of 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 reciprocally moveable in said handle.
Claim 3
Dependent Claim
60 words
The invention in accordance with claim 1 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 4
Dependent Claim
36 words
The invention in accordance with claim 1 in which said reciprocally moveable second handle connecting means is spring biased and is moveable upon application of pressure sufficient to overcome the force exerted by said spring bias.
Claim 5
Dependent Claim
36 words
