Everyday Blade
This keychain-sized retractable knife allows you to carry a razor-sharp hobby and craft blade anywhere. It works with 12 different types of blades for carving, slicing, whittling, and more. Pop the blade off, and it’s TSA-compliant – just buy more blades at your destination.
Crowdfunded projects pose a degree of risk for buyers, so be sure to do your research and fully read the seller's detailed description and production plans before plunking down your hard-earned money.
