You're Replacing Them Because They Bend.\u003c\/h2\u003e\n\u003cp\u003eThe blade that came with your brush cutter is soft enough to be cheap. One meeting with a fence post or a buried stone and it's out of true — and a blade that's out of true shakes the machine, wrecks the bearings and cuts badly for the rest of its life.\u003c\/p\u003e\n\u003cp\u003eThis one is forged from high-hardness alloy steel.

If your trimmer only ever shipped with a line head, it likely isn't rated for a metal blade at all — check the manual first.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it really last three times as long?\u003c\/strong\u003e\u003cbr\u003eThat's the manufacturer's claim against a standard blade, and the hardness and reversible edges make it plausible. Real life depends entirely on what you hit. One encounter with a concrete kerb ends any blade's run.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I sharpen it?\u003c\/strong\u003e\u003cbr\u003eYes, with a file along the existing bevel. Take an equal amount off each edge — uneven sharpening destroys the balance, which is the main thing you paid for.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I know when to flip it?\u003c\/strong\u003e\u003cbr\u003eWhen it starts tearing rather than cutting, and you find yourself pushing the machine into the growth.
