These may look like Klingon weapons from an episode of Star Trek, but they're actually versatile garden tools designed for trimming shoots and stems, cutting vines, severing roots and sawing branches. If you've got an overgrown garden—or one filled with coarse ornamental grasses needing to be cut back—try a 13- or 18-in. billhook saw, which has a rust-resistant, curved blade for quick pull cuts and a coarse saw edge for removing tough branches and grasses. Get a billhook saw on Amazon now.
