All our multi-tool products are manufactured to the highest standards. Our multi-tool components are strong and the knives retain a sharp cutting edge.
Your multi-tool product should be cleaned, dried and re-oiled periodically to inhibit rust and corrosion. This is especially true if you use it in a damp or marine environment. After cleaning, re-oil pivoting areas with a light machine or penetrating type oil (such as WD-40). Buff stained surfaces with a polishing cloth or non-metallic abrasive (e.g., Scotchbrite pad or soft bristle brush).
NB: Stainless steel is not rust proof; it is corrosion resistant.
