Sharpen Hedge Trimmer Blades
Restoring the bevel on hedge trimmer teeth with a fine ceramic grinding disc, following the factory angle rather than recutting it.
Keep a Lawn Edger Cutting Clean With a File, Never a Grinder
Sharpen a lawn edging tool with a hand file, working the existing bevel until the edge is scary sharp. A grinder removes too much steel and overheats the edge — and an overheated edge dents deep on the first rock it meets.

The Problem
A dull edging tool doesn't slice a thin ribbon off the lawn edge — it tears out big chunks, widening the bed and eating into the grass line every pass. And the obvious fast fix, a grinder, makes the tool worse: it hogs off steel and overheats the edge, and overheated steel dents deep the first time it strikes a rock.
The Technique
- Sharpen with a hand file, following the tool's existing bevel — it's a wide bevel, so keep the file riding flat on it.
- Work around the whole edge until it's sharp enough to worry your finger. On a maintained tool this takes minutes.
- Repeat often. The creator files his daily before edging; the point is that a quick file touch-up keeps the edge in the zone where it removes a small sliver of turf instead of a bite.
A filed edge cuts cool steel that stays tough — it deflects off rocks instead of denting — and the thin, controlled cut is what keeps bed lines crisp without growing the bed every season.
Pro tip: His tool of choice is a vintage half-moon edger — older ones were made from steel that holds an edge, where budget modern ones bend or fold their edge over. They show up on marketplace listings for reasonable money.
