Lawn mowers are so closely correlated with cutting grass that it’s easy to forget about the frequently unsung yet equally important string trimmer. A string trimmer—commonly referred to as the “weed whacker”—is a touch-up tool of sorts that is just as capable at clearing large swaths of overgrowth as it is tackling the most delicate touch-ups around fences and posts. To put it simply, string trimmers go where lawn mowers can’t, and if you’re getting serious about putting a clean finishing touch on your lawn and garden maintenance, it’s one tool you shouldn’t go without.

This string trimmer from Craftsman excels at bigger projects like clearing lots of tall brush and weeds thanks to its large 15-inch cutting swath.
