The Elko is a slip-joint folder built to live on a keychain without getting in the way. Designed in Portland, it closes to 2.6 inches and opens to 4.3 inches, with a 1.6-inch drop-point blade in Sandvik 12C27 stainless steel and 6061 aircraft-grade aluminum handles. The backspacer integrates a flat screwdriver, pry bar, and bottle opener, and loops through a split ring to mount the whole thing to a keychain. The slip-joint mechanism requires two hands to open and needs no lock, keeping it legal in most places a larger knife wouldn't be.
