The online community at EDC Forums focuses on the everyday carry lifestyle/obsession, which is basically an interest in items that you always have on you: knives, tools, keys, packs, etc. A small portion of the members take the interest further by customizing tools for specific individual needs, which is pretty cool — one of the coolest is the Keyman mod.
The mod consists of a stripped-down Leatherman with filed-down keys substituted for the tools. EDC Forum member shadeone created the compact, jingle-free, key-carrying solution shown above. You can check out more picks of this and other mods via the links below.
