I use gun oil on all of my tools along with a final coat of Barricade.
Case in hand today I found an old Gerber 1st Generation rev.5 blunt nose multitool in my
fathers car well cleaning it out. He forgot he had it and I forgot I ever bought it and gave it to him.
He told me he never used it and to to keep it. Thanks dad I gave it to you anyway.
Gun oil it chases rust causing moisture and keeps under the car seat gunk from staining the MT.
