Positron was featured prominently in the September 2015 Spyderco Byte newsletter so I was expecting it earlier this month!
"Brad Southards Southard Folder holds the distinction of being Spydercos first flipper-opening folding knife. In addition to paving the way for subsequent flipper designs like the Domino, Dice, and Rubicon, it also whet our customers appetite for more of Southards highly refined, exceedingly practical folder designs. In response to that interest, Spyderco is proud to introduce our second Southard collaboration, the Positron.
Like the Southard Folder, the Positron features a flipper opener. Pioneered by custom knifemaker Kit Carson, a flipper is a small integral tab that extends from the tang of the blade on the cutting edge side. When the blade is closed, the flipper protrudes from the back of the knifes handle to offer a small lever. Pulling on this lever with your index finger creates a tension against the ball-bearing detent mechanism that holds the blade closed. When the detent is overcome, the blade pivots to snap authoritatively into the open, locked position.
Based on Southards popular Ion custom folder, the Positron distills all the best features of a full-sized flipper folder into a compact, pocket-friendly package. The heart of the design is a full-flat-ground PlainEdge blade machined from premium CPM® S30V® particle-metallurgy stainless steel. Although the drop-point blade proudly includes a small Trademark Round Hole as a symbol of the Spyderco brand, it is purpose designed to open only as a flipperanother first in Spydercos product line. The Positrons minimalist flipper provides swift, reliable one-handed opening and in the open position serves as an understated but highly effective guard.
Crafted from solid carbon fiber, the Positrons twin handle scales are meticulously machined, radiused, and polished to provide an amazingly comfortable grip and a stunning appearance. They also house the nested, skeletonized stainless steel liners that form the foundation of the knifes sturdy LinerLock mechanism. The butt end of the handle features a reversible deep-pocket wire clip that provides left or right-side tip-up carry and offers both subtle discretion and immediate access.
Rather than conventional flat washers, the Positrons blade pivots between special washers that contain nested ball bearings. This advanced construction greatly reduces friction on the blade, maximizes the efficiency the flipper mechanism, and ensures a long service life.
The Spyderco Positron faithfully translates Brad Southards distinctive style and superior craftsmanship to a highly refined flipper-style folder that is easy to carry and ideal for everyday use. It will begin shipping in early October and were confident that youll like it just as much as we do."
