F3 Swappable Handle Scale Set (OD Green G10)

Make It Yours

Refresh your everyday carry, match your kit, or build out a collection of looks for every season — the F3 swappable handle scale system lets you transform your knife in minutes with a few turns of a screwdriver. Same trusted F3 platform. New personality.

OD Green G-10

OD Green has been the working uniform of soldiers, woodsmen, and outdoorsmen for the better part of a century — earned in the field, not chosen for fashion. It's the color of well-used gear, of pack straps and surplus jackets and tools that have been somewhere and done something. Subtle enough to disappear against a forest backdrop, classic enough to never go out of style. Pair that quiet confidence with G-10's legendary toughness — impervious to moisture, won't crack in the cold, won't fade in the sun, and tough enough to outlive the knife it's mounted to — and you've got a handle as understated as it is unbreakable. Made for the treeline, the trailhead, the truck bed, and every job you'd rather not advertise.

Each scale set is precision-machined to the exact contours of the F3 handle, preserving the ergonomic geometry that makes the F3 so comfortable to run for hours on end. 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.

Why UltreX® Composites

We could've cut corners and sourced cheap overseas composites. We didn't. Every F3 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.
