Originally billed as "the minimalist key ring with maximum strength," the KeySmart line was invented in Chicago and brought to life by a Kickstarter campaign in 2013 (then the most successful campaign to date). They are robust and thoughtfully designed products that fit most standard keys and require no tools – the posts unscrew with a coin to add or change keys.
KeySmart Rugged is the heavy-duty alternative to the original KeySmart.
Front and back plates are 3mm thick. Assembled with two stainless-steel posts and screws, it is also supplied with a loop ring and bottle opener (each uses one key space) as well as a removable pocket clip and a pair of expansion screws to increase capacity to up to 14 keys.
Additional accessory tools (each replaces a key) are available separately.
