ABSTRACT:
A string trimmer provides a cutting head having a passage therethrough receiving a cutting element of fixed length. The cutting element includes a monofilament line and a resilient sleeve surrounds one end of the monofilament line. A rigid eyelet in one end of the resilient sleeve provides an external upset or abutment which cooperates with a shoulder or restriction in the passage to retain the cutting element in the passage during cutting. A groove in the periphery of the cutting head intersects the passage and provides a recess for wholly receiving the cutting element if the user positions the cutting head against an immovable obstacle.
