WORX - 4V ZipSnip Electric Rechargeable Cordless Electric Scissors, Fabric Scissors, Rotary Cutter with self sharpening blade

$34.99

The Worx 4V ZipSnip Cordless Electric Scissors are designed to do everything traditional handheld scissors can—and more. Powered by a rechargeable 4V Max Lithium battery, this cutting tool spins a rotating blade that can cut through various materials up to ¼” thick—including tough plastic packaging, cardboard, fabric, rubber, leather, and wrapping paper. Its self-sharpening blade keeps the edges fine to deliver a precise cut with every use. While the cutting capabilities are powerful, the ZipSnip is optimized for safety. The safety switch works in conjunction with the trigger to prevent the blade from moving unintentionally. The blade guard also blocks the sharp edge to prevent accidental cuts. The cutting tool weighs only .86 lbs. and features a textured GRIPZONE handle to optimize comfort during extended projects. And with its compact and cordless design, the ZipSnip can be conveniently maneuvered in the home, kitchen, garage, and garden. While the battery maintains its charge for several months, it can be recharged in just a few hours using the included charger—so you’ll always have a cutting tool ready to use.

4.7(21)

$89.99

You can inflate all the tires on the car and then some with the Worx 20V Power Share Portable Inflator. It fills up 4.5 tires on one charge. And it goes from 0-36 psi in about 4 minutes per tire. That’s faster and more efficient than inflators from other brands. And you don’t have to plug it into your car’s DC port and then park some place that’s convenient to use it. With the powerful 20V battery (that’s the same one we use on our leaf blowers and cordless chainsaws, by the way), you just bring the inflator wherever it needs to go. Take it to the pool, the dock, even pack it for a long bike ride, it’s the ultimate in portability and convenience. The LED lamp outputs 100-200 Lumens and can be used as a work light so you can see what you’re doing, a flashlight if you need to take a walk in the dark to a service station, even an emergency beacon to alert other motorists that you need assistance. The flexible 2.3-foot hose lets you reach nozzles and stems that are hard to get at, and it comes with 3 adaptors: 1 sports ball needle, 1 Presta and bike valve adaptor, 1 tapered adaptor for small inflatables like pool toys. Plus, the soft-grip handle is comfortable to hold and use for long stretches. Keep the Worx 20V Power Share Portable Inflator in your trunk and gain the peace of mind you get from being prepared.
