Care

ESSENTIAL ROUTINE MAINTENANCE

Regular maintenance is fundamental to preserving the efficiency, reliability, and lifespan of your product. After each use – especially in the presence of salt water, humidity, mud, or grease residues – rinse with fresh water, dry thoroughly, and apply a suitable lubricant to metal parts and moving mechanisms. Periodically inspect the inside of the sheath, removing sand, dust, or abrasive particles that could damage the blade finish when sheathing or unsheathing.
