How to use and care
Rinse in fresh water after every dive, disassemble it to remove salt and sand, dry the parts and lightly oil the blade if you store it for a long time. Carry the knife where it can be reached easily with either hand, and keep the edge protected in the sheath when not in use. The knife is a practical backup for freeing yourself from lines and for dealing with a catch, and it is best carried in an accessible position on the leg or forearm. Check the sheath fixation before each dive so the knife stays where you expect it. Store the knife dry and keep it out of the reach of children, as it has a sharp blade.
