3. Setup
3.1 What's in the Box
Your Kershaw Funxion EMT knife package includes:
- One (1) Kershaw Funxion EMT Assisted Opening Knife (Model 8100GRYST)
3.2 Initial Inspection
Upon receiving your knife, inspect it for any signs of damage or manufacturing defects. Ensure the blade opens and closes smoothly, and all integrated tools function as expected. If any issues are found, refer to the 'Warranty Information' section.
4. Operating Instructions
4.1 Opening the Blade
The Kershaw Funxion EMT features a SpeedSafe assisted opening mechanism. To open the blade:
- Using the Flipper: Apply downward pressure to the flipper tab located on the spine of the handle. The blade will quickly deploy and lock into place.
- Using the Thumb Stud: Apply outward pressure to the thumb stud on the blade. The blade will deploy and lock into place.
Ensure the blade is fully locked before use. The SpeedSafe mechanism is assisted, not automatic.
4.2 Closing the Blade
To close the blade, disengage the liner lock:
- Locate the liner lock, which is a metal bar inside the handle, pressing against the base of the blade.
- Push the liner lock to the side, away from the blade's path.
- Carefully fold the blade back into the handle until it is fully closed. Keep fingers clear of the blade path.
4.3 Using the Integrated Tools
The Funxion EMT includes several integrated tools:
- Cord Cutter: Fold out the cord cutter from the handle. It locks into place with a leaf spring mechanism. Use the sharp hook to cut cords, seatbelts, or similar materials.
- Hex Wrench: The cord cutter also features a hex wrench opening.
- Carabiner Clip: Fold out the carabiner clip from the handle. It can be used to attach the knife to gear or a belt loop. When the carabiner is engaged, the blade is locked to prevent accidental opening.
- Glassbreaker Tip: The pointed tip at the end of the handle can be used for emergency glass breaking.

5. Maintenance
5.1 Cleaning
To maintain your knife's performance and appearance, follow these cleaning guidelines:
- Hand Wash Only: Clean the knife by hand using mild soap and water. Avoid harsh chemicals or abrasive cleaners.
- Rinse thoroughly and dry immediately with a soft cloth to prevent rust or water spots.
- Ensure all moving parts, especially the pivot area, are free of debris.
5.2 Lubrication
Periodically apply a small amount of light oil (e.g., mineral oil or specialized knife oil) to the blade pivot area. This helps maintain smooth assisted opening action and prevents corrosion.
5.3 Sharpening
The 8Cr13MoV stainless steel blade will retain its edge well, but regular use will eventually require sharpening. Use a quality sharpening system appropriate for a partially serrated blade. If you are unsure, seek professional sharpening services.
5.4 Screw Tightening
Over time, screws on the handle or pocket clip may loosen. Periodically check and tighten all screws using appropriate Torx drivers to ensure the knife remains secure and functional.
6. Troubleshooting
- Blade not opening smoothly: Check for debris in the pivot area. Clean and lubricate as described in the Maintenance section. Ensure the liner lock is not partially engaged.
- Blade not locking securely: Inspect the liner lock for damage or obstruction. Ensure the blade is fully deployed. If the issue persists, discontinue use and contact support.
- Tools sticking or difficult to deploy: Clean any dirt or grime from around the tool pivots. Apply a small amount of lubricant if necessary.
- Loose screws: Refer to section 5.4 for tightening instructions.
