MachineWise Sonora #2191 Purple to Blue Fade Anodized Diamond Textured Titanium Brass Bolster S90V Lightwash Button Lock Flipper (3.35" Blade)

The purple to blue fade on this MachineWise Sonora shifts color as you turn it, and diamond texturing across the titanium adds a premium feel under the fingertips. An integral titanium flipper, it pairs a Lightwash S90V blade with a button lock for general cutting.

• S90V Lightwash Drop Point Blade - A premium powder stainless, S90V is carbide-dense enough to hold an edge longer than most stainless steels, at the price of needing diamond or CBN plates to bring it back. An ultra-fine Lightwash finish cuts glare, and the grind runs thin behind the belly, getting a touch thicker towards the tip for added strength.
• Purple to Blue Fade Anodized Diamond Textured Titanium Handle - Diamond texturing is cut straight into the integral titanium frame, machined in rather than added on. The anodized fade runs purple through blue down the handle, and the brass bolster brings warmth and a little weight up front.
• Stainless Bushing Pivot - A stainless bushing pivot tuned to tight tolerances lets the blade flip fast and free off the flipper tab. The action stays glassy from the first press, with no grit and no wobble. This ranks among the smoothest folders in the class, and it fires the same way every time.
• Raw Titanium Deep-Carry Clip - Milled titanium, tumbled and left unanodized, the clip hangs on one hidden screw and sits low enough that only it shows above the pocket. It can be mounted to either side using the included T15 bit in the box.

The MachineWise Sonora

The MachineWise Sonora is the first folding knife from a small five-person shop in Phoenix, Arizona. It carries into an everyday format the flipper background that MachineWise earned building balisongs, built around a button lock for secure, repeatable lockup and quick one-handed use. The frame is an integral, cut from a single block of Grade 5 titanium so the whole handle is one solid piece instead of a sandwich of slabs and hardware. Every Sonora leaves the shop numbered, with the blade hardness tested and written on the QC card in the box.
