Requires proper use – the blade should only be used for cutting and should not serve as a pry tool or striking instrument.

Regular sharpening – as with any cutting tool, the edge must be maintained continuously to preserve good performance.

To keep the CRKT Sero Crossbar Lock 7170K operating smoothly, locking reliably, and maintaining a sharp edge, regular basic maintenance is recommended:

• Blade cleaning: After use, wipe the blade with a soft cloth and remove any dirt. After contact with water or moisture, always dry it thoroughly.
• Crossbar Lock maintenance: Regularly remove dust and dirt from the mechanism, as these can affect smooth operation.
• Mechanism lubrication: The pivot and moving parts can be lightly lubricated as needed with a quality oil intended for knives. Use only a small amount.
• Screw check: Regularly check the tightness of the handle, clip, and mechanism screws.
• Handle care: Clean the handle scales with a soft cloth and a mild cleaning agent. Avoid aggressive chemicals and abrasive products.
• Pocket clip: Check its attachment and inspect for signs of deformation or damage.
• Sharpening: To maintain proper edge geometry, we recommend a quality sharpening system with a controlled angle, for example the Spyderco Tri-Angle Sharpmaker Complete Sharpening System 204MF.
• Blade protection: For long-term storage, it is advisable to lightly treat the blade with a suitable preservative oil and store the knife in a dry place.

Important: Use the knife as a cutting tool. Do not use it for prying, chopping, striking, or other activities that may damage the blade or the Crossbar Lock mechanism.
