The RR3 in the 'Classic Stonemilled' variation

A brand new design from ATR & Knife Standards

Dedicated to my Father RR, this design is the next step in the Knife Standards journey. The RR3 integrates familiar lines and brand new features to make it an easy choice for everyday carry. The RR3 is my smallest design yet and my first liner lock. The smaller size and sleek silhouette make for a low profile, comfortable carry. 

We are using Vanax SuperClean blade steel for The RR3 which is an extremely corrosion resistant steel. The full flat ground drop point blade is perfect for everyday carry tasks, and can be deployed with both the dual thumbstuds and the front flipper. 

The RR3 'Classic Stonemilled' features a nested inset liner lock, Stonemilled 6AL-4V titanium handles, carbon fiber inlays, a wire clip and a tumbled DLC belt satin finish on the blade. The 'Classic Stonemilled' variation is timeless, unique, and ready for carry.
