Why the heck did no one invent this sooner?! The Snapback Chalk Line is the world's first self-releasing chalk line – and it'll save you countless footsteps, not to mention time and frustration, every time you use it. It works just like a standard chalk line tool, except once you've laid down your chalk guide, snap the line away from your body to release the clip, then reel it in as usual -- without walking to retrieve it. Now that's a step in the right direction!
