3. Setup and Initial Inspection
Upon receiving your Sitivien ST26 Fixed Blade Knife, perform the following steps:
- Unboxing: Carefully remove the knife and sheath from its packaging.
- Visual Inspection: Examine the knife for any signs of damage, manufacturing defects, or loose components. Ensure the blade is securely attached to the handle.
- Sheath Fit: Test the Kydex sheath for proper retention. The knife should snap securely into place and require a firm pull to release, but not be excessively difficult. Adjust the clip if necessary for your preferred carry style.

4. Operating Instructions
The Sitivien ST26 is a versatile tool. Always prioritize safety and use appropriate techniques for each task.
General Handling
- Always maintain a firm grip on the handle.
- Keep your fingers clear of the blade path.
- Cut away from your body whenever possible.
Cutting Techniques
- Push Cuts: For precise cuts, apply steady pressure and push the blade through the material.
- Slicing: Use a drawing motion to slice through materials, utilizing the full length of the blade.
Batoning
The robust construction of the ST26 makes it suitable for batoning. Use a sturdy piece of wood to strike the spine of the blade, driving it through larger pieces of wood for splitting.
Feathersticking
The sharp N690 blade is excellent for creating feathersticks, which are fine wood shavings used for fire starting. Hold the knife at a shallow angle to the wood and push the blade along to create thin curls.
Fire Starting
The sharp 90-degree spine of the ST26 blade can be used effectively with a ferrocerium rod to create sparks for fire starting. Scrape the ferro rod with the spine over tinder to ignite it.
Sheath Usage
- Insert the knife into the Kydex sheath until it clicks, indicating secure retention.
- To draw, grip the handle firmly and pull the knife straight out with a deliberate motion.
- Utilize the adjustable clip to customize your carry position on a belt or gear.

5. Maintenance
Proper maintenance ensures the longevity and performance of your Sitivien ST26 knife.
Cleaning
- After each use, especially after contact with food, acidic substances, or saltwater, clean the blade and handle thoroughly.
- Use warm water and mild soap. Avoid harsh chemicals or abrasive cleaners.
- Dry the knife completely with a soft cloth to prevent water spots and corrosion.
- Apply a thin layer of food-grade mineral oil to the blade for added protection, particularly if storing for extended periods.
Sharpening
- Maintain the blade's sharpness regularly using a quality sharpening stone or system.
- If you are unfamiliar with sharpening techniques, seek professional sharpening services to avoid damaging the blade.
Storage
- Store the knife in its Kydex sheath in a dry environment.
- Keep out of reach of children and unauthorized users.
- Avoid storing in damp or humid conditions to prevent rust.
6. Troubleshooting
- Dull Blade: If the blade loses its sharpness, refer to the sharpening instructions in the Maintenance section.
- Minor Rust Spots: Small rust spots can often be removed with a fine abrasive pad (e.g., Scotch-Brite) and then re-oiled. For persistent rust, professional attention may be required.
- Loose Handle: Periodically check the handle screws for tightness. If they become loose, gently tighten them with an appropriate screwdriver. Do not overtighten.
- Sheath Retention Issues: If the Kydex sheath loses retention, it may be possible to adjust it by carefully heating and reforming the Kydex, or by adjusting the tension screws if present. Consult manufacturer guidelines or professional advice if unsure.
7. Safety Information
Always exercise extreme caution when handling any knife. Improper use can result in serious injury.

- Cut Away: Always cut away from your body and other people.
- Stable Surface: Use the knife on a stable surface to prevent accidental slips.
