ABSTRACT:
An improved clipper and improved cutter head attachment device of the type having a pair of mating members including a substantially flat male member and a female slot. One of the mating members has at least one resilient offset portion which must be squeezed into engagement against the other of the mating members when the cutter head is engaged with the main clipper body. This provides gap-free engagement which reduces noise and improves cutting performance.
