F3 Swappable Handle Scale Set (Black 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.

Black G-10

Black is the default for a reason. It's the color that doesn't need to explain itself — pairs with every kit, every wardrobe, and every environment from the office to the jobsite to the backcountry. Where other colors make a statement, black just gets to work. It hides wear, shrugs off whatever the day puts on it, and doesn't telegraph what's on your hip — looking every bit as sharp after a decade of daily carry as it did on day one. Pair that quiet capability 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 that disappears when you want it to and performs when you need it to. Made for the suit pocket, the work belt, the go-bag, and every job that gets done without an audience.

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.
