Information from the Spyderco catalog on the web

C177 Roc:

"Designed by custom knifemaker Serge Panchenko, the Roc combines an unusual cleaver-style blade with a gracefully curved handle and a sturdy LinerLock mechanism to create a uniquely functional cutting tool that challenges convention. Precision ground from VG-10 stainless steel, the Roc’s blunt-tipped, PlainEdge™ blade features a low-profile matte gray finish and a saber grind that balances high-performance edge geometry with the strength and heft of a full-thickness spine. A long section of jimping (textured grooves) on the blade’s spine provides a solid purchase for the user’s thumb, and an easily accessible Trademark Round Hole™ ensures swift, positive one-handed opening with either hand.

The Roc’s handle combines full skeletonized stainless steel liners with textured G-10 scales and an open-backed construction that reduces weight and simplifies cleaning and maintenance. Its thick liners also form the foundation of the knife’s sturdy LinerLock mechanism, which includes a Bob Terzuola-inspired concave lock ramp on the blade’s tang. To ensure convenient carry and immediate access, the Roc features a reversible deep-pocket wire clip attached to the butt end of the handle to offer left or right-side tip-up carry."
