Our Breakthrough HP100 Knife Oil with SMT (Sub-Micron Technology) has been engineered to protect and enhance the performance of today's sophisticated folding knife mechanisms. This non-migrating non-toxic formula, once applied, will fill the surface disparities between the bearing, surface of the blade and surrounding handle, allowing for smoother operation and prevention of corrosive elements from damaging the mechanism.
