I have a Benchmade knife made of D2 tools steel. I treated my knife with frog lube. One night during a snow storm I received a fire call. I’m within walking distance from my fire station so I always run there for calls. During this run I lost my knife. I looked everywhere after the call and couldn’t find it. It was was my favorite so I was pretty bummed. Three months later after the snow melted I found it in the mud and leaves. I was expecting the worst knowing the properties of D2. I was surprised to find just some rust around the thumb stud and some on the part where my thumb rests. I told this story to Benchmade and they thought I should share it with you. I’m a customer for life.
