C159 Air

The C159 Air was introduced in 2012 and is a small folding gentleman's knife designed by Gayle Bradley. A few notable features of the Air are the CPM M4 steel blade, the silver twill glass fiber laminate handle scales, and the fact that it was designed for pocket carry without a pocket clip.

Information from the Spyderco catalog on the web

"The Air is meticulously manufactured from premium materials that literally allow it to live up to its name. Its handle is built on a foundation of full-length titanium liners that also support the structure of its Walker LinerLock mechanism. Skeletonized to reduce weight, the liners are covered with silver twill glass fiber laminate scales that provide a lustrous three-dimensional appearance and just enough texture for a secure grip. An open-back construction style further reduces the weight of the knife and allows for easy cleaning, while its unique internal stop-pin construction supports an exceptionally narrow, pocket-friendly profile.

The heart of the Air is its CPM M4 Wharncliffe-style blade. Combining a perfectly straight cutting edge with full-flat-ground bevels, it provides outstanding cutting performance for its size. A decorative swedge on the spine adds a visual accent to the design and provides a comfortable index-finger perch for scalpel-like control when cutting with the tip. Spyderco’s Trademark Round Hole nests comfortably in a scalloped recess in the handle when the blade is closed. More convenient and accessible than a traditional nail nick, it allows convenient opening with either one or two hands.

In the open position, the Air’s blade locks firmly via a LinerLock mechanism. To release the lock, two relief cutouts are provided in the opposite handle liner. One also serves as an access relief for the Round Hole, while the other, which is closer to the pivot pin, provides extra leverage for easy operation.

Unlike most Spyderco folding knives, the Air does not have a pocket clip. By design, it is a gentleman’s folding knife and is therefore intended to be carried inside the pocket.

The Air is a distinctive fusion of Gayle Bradley’s design talents and Spyderco’s tradition of innovation. The result is a new standard in gentleman’s pocket knives that offers both practical cutting performance and great pride of ownership."
