Got a slippery handle on your hammer or rake? Wish your wheelbarrow handles were a bit more comfy? The Re-Grip (re-grip.com) makes it easy to add or replace rubber handle covers on all kinds of tools. No gluing or heating necessary—you just insert the handle of the tool and pull on a plastic tab to unwind the plastic coil from inside the rubber cover, which then shrinks to fit around the handle. Re-Grip comes in three sizes, which cost $9 to $17 online.
