I purchased a Benchmade 5370FE Shootout about 9 months ago. Somehow the Deploy / Retract button broke and disappeared. I don't know what happened to it. I had the knife clipped on to a fanny pouch waist strap while cycling so the entire knife was exposed. I got home, took off the pouch and knife, and the button was gone. I called Benchmade, they sent me shipping info, and I sent the knife to them. 9 days later, I had it back. The knife looks new and functions even smoother than it did originally. I have a few Benchmades, but I never needed service on them. What a stand-up company. Thier customer service is excellent! I don't post much, but I find fewer and fewer companies truly stand behind their product and wanted to share my experience.
