Unsurprisingly, the project has already blasted past its initial $35K funding goal, and is currently sitting at well over $50K. You won’t be able to find it at your local hardware store yet, but Pinckard has filed a provisional patent for the bit’s design, and launched a Kickstarter to jumpstart production. As you’ve probably guessed from the name, the bit’s unique geometry causes it to dig into the screw head and lock in place when lots of torque is applied, so instead of slipping out and demolishing your screw head, it actually gets tighter. eventually, it will either loosen up and start turning, or you will be. eventually, the screw will get stripped a bit - this is GOOD. To remedy this problem, inventor Dan Pinckard has developed an ingenious new Phillips bit, dubbed the Knife Edge, that not only prevents cam out from happening, but also allows you to turn damaged and otherwise unusable screws. Yes, I have found a working trick to do it All you need is a flathead screwdriver about the size of the triwing screwdriver yyou would need so, all you do is stick the flathead on the screw at an angle, sort of lying on its side, and keep trying to turn it.

The screws used back then were made of higher quality steel than the ones you currently buy at Home Depot, so this was an important feature at the time.
They were invented back in the 1930s for use on automotive assembly lines, and their creator Henry Phillips deliberately designed them to “cam out” or push themselves out of the screw at a certain point so that they wouldn’t damage cars on the assembly line. You know what I’m talking about - one false move and the bit will push itself out and mangle the screw head, making it difficult (or downright impossible) to drive/remove the screw.Įver wonder why this happens? Well as it turns out, it’s because that’s exactly what Phillips screwdriver bits are designed to do. Turning a screw should be a pretty straightforward task, but for some reason, the shape of a Phillips bit makes it a delicate affair. If you’ve ever used a Phillips screwdriver, you know firsthand just how frustrating they can be to work with.
