Tom and Dan are back on Kickstarter with a new product named Keen, a very clever utility knife:
Like our Mark One pen, Keen is a simple object with a single interface, in this case the slider. Our job was so make that interaction as satisfying as possible, so that Keen is a delight to use every time you pick it up. We spent a lot of time getting the feel of the blade deployment just right. It is spring loaded, requiring just the right amount of force to slide out, and to not be too fatiguing when held out. When cutting, the slider is held by your thumb, then simply released to suck the blade back in. Not only is this satisfying every time, it’s safer, as the blade can never be left in the “out” position. An internal magnet helps secure the blade when closed, and adds a satisfying snap to the deployment.
Insta-backed.
