Description

The ULTRAMARINE is an amphibious knife.

Two different versatile sheaths were therefore developed for it. The scuba sheath can be worn at the ankle, or its hard ABS section can be attached by two BELT-CLIPS to either the breathing apparatus or BCD belts.

The land sheath (OPTIONAL, included on request) is MOLLE system compatible, designed to be attached to the tactical vest and carried inside a waterproof bag during underwater operations. All an operative has to do, if getting rid of his trilaminate drysuit after landing, is to draw the knife from its ankle sheath and place it in the tactical vest sheath.

Primary functions: field operations, underwater operations, emergency tool, survival and combat.

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.
