A new Kickstarter campaign takes cues from high-end outdoor/military knives to create a stainless steel EDC multi-tool card. The bottom line for the Cleveland-based designers Cha-O-Ha was making a product that takes up little space, while offering a bevy of useful functions. The tool represents the essence of modular design, embodying the versatility that comes along with 30 different functions, all built into something the size of a credit card. Make your contribution to Cha-O-Ha’s Kickstarter campaign, which has already reached its goal and is set to be funded on October 16.
