ABSTRACT:
A manually operable lawn-edge trimming implement consists of a blade-carrier, a knifing blade and a broom-stick handle by which the implement may be presented to the lawn edge and traversed therealong with the blade obliquely penetrated into the earth along the line of edge trimming. The blade-carrier acts as a clamp for removably holding the replaceable knifing blade, and the blade-carrier is supported by an axle on two wheels which are well spaced apart so as to prevent grass crushing in the lawn-edge vicinity.
