A string trimmer, also calle a line trimmer, Weedeater (a brandname), Weedwhacker(a brandname), Weed Whip, weedy, whipper snipper, "Strimmer" is correctly a tradename, but it has slid into British English use as a genericized trademark and spawned a back-formed verb "to strim" = "to use a string trimmer on".</ref> garden strimmer is a powered handheld device that uses a flexible monofilament line instead of a blade for cutting grass and other plants near objects. It consists of a cutting head at the end of a long shaft with a handle or handles and sometimes a shoulder strap. String trimmers powered by an internal combustion engine have the engine on the opposite end of the shaft from the cutting head while electric string trimmers typically have an electric motor in the cutting head.
