Do-It-All Saw. According to Irwin, the new Universal Handsaw is the only saw you’ll ever need. The blade’s triple-ground tooth design cuts three times faster than a typical saw blade, produces cuts with a fine, smooth finish, and won’t bind, the company says. Irwin also claims that the saw’s ergonomic handle-to-blade configuration makes it easier to start a cut. The tool comes with a 15-inch blade ($19) or a 20-inch blade ($22). Irwin Tools, 800/464-7946,
