Titan Obsidian Edge, always within reach

Distinct by design

Loose, forgettable tools get left behind. The Titan Obsidian Edge EDC Blade TK-121 anchors the daily kit with a 3.5-inch blade and an 8-inch overall footprint that feels considered rather than cumbersome. Its hand-stitched cowhide sheath keeps it close to the belt and out of the way until the task appears. The patterned steel and deep-toned Black Diamond handle turn a routine reach into a sure one.

Confidence you can hold

When gear earns a place on your person, it should pull its weight—quietly. The TK-121 carries a tough, durable edge and a grip shaped for real work, not display. The leather sheath with brass snaps secures the knife so your hands are free until they need precision. This is the piece that stays put, day after day.

For the ones who carry

Someone who keeps a dependable blade on belt or pack and appreciates a finely patterned edge and hand-finished leather.

Where it lives

Clip the hand-tooled leather sheath to a belt loop and reach for the 3.5-inch blade when opening packs, trimming cord, or handling small camp tasks.
