Acid Washed Brass Scales with Lazar Etch and Tool Steel Core

Brass alloy 260 also known as "cartridge brass" scales.   All of the great brass hues, with much better strength and wear resistance in comparison to common brass alloy 360.  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!
