Use & Care

• Proper care and regular maintenance help make your Benchmade knife yours, for life. Here are some tips for keeping your Benchmade in peak condition
• All steel, regardless of price and grade, can eventually rust, so it’s important to keep your knife dry and lubricated. If spotting or rust occurs, semi-chrome metal polish will often take care of it.
• Dishwashers can cause serious damage that is not covered under our warranty, so make sure to hand-wash your Benchmade under warm water with dish soap only, and dry thoroughly.
• Remember, knives are cutting tools, and you should never use your knife as a pry-bar, screwdriver, chisel, or punch, unless the knife is designed explicitly for those purposes.
• If you choose to sharpen your blade yourself, avoid grinding wheels and other high-powered machinery.
• Handle, pivot, and pocket clip screws may require occasional adjustment using T6 & T10 Torx drivers. We recommend applying a small dab of releasable thread-locker as needed.
