A toilet flusher in which the plastic lift arm normally hidden from view inside a toilet tank comprises a bi-concave segment readily bent by hand, allowing the toilet flusher to integrate well with a wide variety of flush mechanisms already found installed inside toilet tanks. Bending forces are concentrated along a line rather than at a point, so that the inadvertent cracking of the lift arm during on-site modification that sometimes occurs in lift arms having cruciform cross sections is much less likely to occur.
