How to Install Scales on Your Half Face Blades Knife

Quick answer

To install new scales on your Half Face Blades knife, remove the existing scales, align the new G10 set, and tighten the Allen bolts to spec.

Step-by-step installation

1. Remove the old scales: Use a T6 or T8 Torx driver (depending on your knife) to unscrew each Allen bolt. Keep the bolts in a safe place. Gently pry the scales away from the tang; they may be held by friction or a light adhesive. Work over a soft surface to avoid losing small hardware.
2. Clean the tang surface: Wipe the exposed metal tang with isopropyl alcohol to remove dirt, oil, or adhesive residue. Let it dry completely before mounting the new scales. A clean surface prevents gaps and ensures the scales sit flush.
3. Align and attach the new scales: Place the new G10 scale onto the tang, aligning the screw holes. Insert the supplied Allen bolts and tighten them in a crisscross pattern to distribute pressure evenly. Stop when snug—overtightening can crack the scale or strip the bolt head. Check for any side-to-side play after tightening; if present, loosen and realign before final torque.
