EASY-CUT 1000 have built-in multiple blade-depth settings that makes cutting single, double or even triple walled corrugated cardboards and boxes a breeze with superb control and fluidity. Designed with the user first, a gentle squeeze of its ergonomic handle extends the blade naturally. No need for continuous and repetitive thumbing action, thus greatly reduce the risk of injury that is common with other knives and box cutters. When the user is finished with cutting, simply release the handle, and the blade retracts automatically. ncluded in this set is an original clip-on holster and lanyard (stretches up to 6 feet!) with 360-degree rotation offers convenient and safe storage – reducing injuries and down-time looking for lost cutters! The dual-sided edge guide enables left- and right-handed users to make quick, accurate top cuts, and slides back into locked position when the cut is complete. The on-board blade storage enables fast and tool-free blade changes.
