Build the F5 GEN2 you want to carry into the woods — match your pack, match the season, or just dial in the look of a knife that's already proven itself on the toughest jobs. The F5 GEN2 swappable handle scale system lets you transform your fixed blade in minutes with a few turns of a screwdriver. Same trusted F5 GEN2 platform. New personality.
Natural Canvas Micarta is the original — the warm tan of the Westinghouse-era handle material that's been put to work in the field for over a century, before anyone needed a color chart to choose a scale. Cotton canvas, phenolic resin, heat, and pressure: that's it. No dye, no pigment, no marketing — just the honest color of the materials themselves, unchanged for a century, unimproved upon since. The woven texture telegraphs every layer of the build, and the surface drinks in oil, sweat, and use until your handle is unmistakably yours. No two ever age the same. Same recipe. Same color. Same grip that gets stronger when wet, same stability through every season, same toughness that outlasts the knife itself. A handle that wears in instead of wearing out. Built for the working hands who came before, and the ones still doing the job today.
Each scale set is precision-machined to the exact contours of the F5 GEN2 handle, preserving the ergonomic geometry that makes the F5 GEN2 comfortable to run through batoning, chopping, and a full day of bushcraft. The contoured shape mimics the natural curve of your palm, distributing pressure across your hand so you can grip, cut, and pry without hot spots or fatigue. Drop them on, get back to work — the comfort doesn't change. Only the look.
We could've cut corners and sourced cheap overseas composites. We didn't. Every F5 GEN2 scale is machined from authentic UltreX® G-10 or UltreX® Micarta® — the same materials trusted by true professionals and the original Westinghouse-pioneered Micarta® formulation, modernized for today's demands. Made by Norplex-Micarta in Postville, Iowa, USA.
