How to Finish GripX™ Composite Material

GripX™ is engineered to deliver reliable traction, durability, and control—even in wet conditions. Unlike many handle materials, GripX does not rely on surface coatings or sealers to perform. That means finishing is simple, consistent, and flexible depending on the feel you want.

This guide explains the best practices for finishing GripX so you get the most out of the material.

Step 1: Shaping & Profiling

GripX machines similarly to other composite handle materials.

• Shape using belts, files, or CNC equipment

• Use moderate speeds and sharp tools and belts to avoid excessive heat

• Expect consistent cutting with minimal chipping

GripX’s performance is built into the material, so there’s no need to plan for special surface treatments during shaping.

Step 2: Sanding (Less Is More)

Sanding has the biggest impact on how GripX feels in hand.

Recommended Grit Ranges

• 220 grit: Maximum texture and aggressive traction, less labor

• 400 grit: Balanced grip with a cleaner appearance

• 600+ grit: Smooth finish with slightly reduced bite

For most knife and tool applications, stopping between 220 and 400 grit provides an ideal balance of comfort and control.

Avoid over-sanding if traction is the priority.

Step 3: Surface Cleaning

After sanding:

• Blow off dust with compressed air

• Wipe the surface with a clean, wet rag

• Allow the material to fully dry

• Alternatively, use an ultrasonic cleaner

This ensures consistent texture and removes sanding residue before use.

Step 4: Sealing & Finishing Options

GripX does not require sealing or finishing to perform correctly.

Common Finishing Choices

• No finish: Maximum grip and intended performance, slightly dulled color

• Light wax (recommended): Enhances color slightly and with the use of food-safe RockWax, rubber will swell over 2-5 days and increase grip - this will take several days for the best results to appear

• Thin oil coat: WD40 or other oils can be used similarly to wax

Avoid thick clear coats, epoxy finishes, CA coating, or heavy polishing, as these can reduce the traction GripX is designed to provide.

Step 5: Final Feel Test

Once finished:

• Additional oils from handling will continue to improve grip

• Customers may clean with dish soap or alcohol to restore the initial grip
  

GripX maintains its performance over time because traction is inherent to the composite—not added as a surface treatment.

Frequently Asked Questions

Can GripX be polished?
It can be polished, but this is not recommended if maximum traction is desired.

Will finishing affect durability?
No. GripX’s durability is built into the material and does not depend on finishes.

Is GripX suitable for hard-use tools and knives?
Yes. GripX is designed for real-world use, including wet and demanding environments.

Final Thoughts

Finishing GripX is intentionally straightforward. Shape it, sand to your desired texture, clean the surface, and it’s ready to go. Whether left raw or lightly finished, GripX delivers dependable traction and control without added coatings or maintenance.
