Makes a tool a pleaure to use, one way to describe this knife..... it is a very tough and useful sailors knife. Its blade is fixed in the middle and can rotate so only half of it is exposed, one side has a strong blade and the other is a tool, used to repair fishing nets, unshackling etc... no other tool is needed. It has a very safe blade and is easy to work with. It comes with a magnificent leather holster.
