Tool Steel Core with Acid Washed Hawaiian Etch Copper Scales

We've selected copper alloy 110 for fans of copper and red hues.   Copper 110 has good wear resistance and durability.  These are custom etched, acid washed then tumbled giving them a textured patina feel.  Both the titanium gate and titanium fasteners are custom anodized for a striking look.

STRATO -- Cores 

This custom STRATO-Biner with the tool steel core offers greater strength, wear resistance and utility.  The Tool Steel STRATO core also offers extra jimping and a pry bar for more utility and function.

Strategic Jimping

The design is a result of a multitude of ergonomic tweaks. Jimping is strategically placed for the various utilities within the design.

All new gate design for STRATO!

We've designed an integrated, asymmetrical gate that offers great torsional rigidity for a lifetime of use. As with all of the carabiners made by Ti2 Design, the gate is made from grade 5 Alloy (6Al4V) and features an ambidextrous design allowing positive action right or left handed.
