Questions, answered
Is a trimmer edger as good as a dedicated edger?
For maintained edges, yes. The Worx pivoting head cuts a clean vertical line along sidewalks and driveways. Dedicated walk-behind edgers cut deeper, which matters only for overgrown or first-time edging.
What line works best for edging?
Thicker line holds its shape against pavement longer. If you edge often, a trimmer with 0.080-inch or thicker line will need fewer line advances.
How do the other trimmers edge without a pivoting head?
You rotate the shaft so the cutting plane is vertical and walk the line along the pavement edge. It works, but keeping a consistent depth takes practice compared to the Worx pivot.
