Daiwa makes this light, odorless oil in the USA as a fishing reel oil. It is also used by many folding knife owners as a knife oil. The fine needle nose allows you to get oil to the knife bearings and pivot without disassembly and enables careful control of where the oil goes. If you are purchasing one of our Skaha folding knives and you don’t already have a good oil, this one will help keep it running smoothly. You only need a few drops at a time, so one tube will last most users a long time.
