Clipper blade assembly
First Claim
1. A blade assembly for use with a hair clipper, the clipper including a handle with a drive end, a drive member extending from the drive end, and a first coupling formation disposed at the drive end, said blade assembly comprising:
- a housing having a fixed blade and a moving blade reciprocating relative to said fixed blade, a second coupling formation configured for engaging the first coupling formation, said second coupling formation being configured for accommodating the drive member, said housing also having blade locating means for locating said fixed blade thereon;
said blades being substantially identical, each said blade configured for use as either of said fixed blade and said moving blade, each said blade having a web portion, a first cutting edge and a second cutting edge, said first cutting edge being longer than said second cutting edge, said web portion further including a pair of longitudinal guide slots extending substantially parallel with said cutting edges, said guide slots being disposed closer to said second cutting edge than to said first cutting edge; and
said first cutting edge being configured for application as the fixed blade, and said second cutting edge being configured for application as the moving blade, wherein one of said pair of blades serves as said moving blade by employing said second cutting edge, and the other of said blades serves as said fixed blade by employing said first cutting edge.
