I purchased this knife June 9, 2013. Within two weeks I gave it to my 9 year old boy. He lost it within a week. It was found last week out near a barn on our property by my 5 year old girl...So almost 10 months out in an area that gets some truck/tractor traffic, it hardly had any rust. Whatever there was he easily sanded off, and just a small amount of pitting was evidenced. Little soap and water on handle and oiled pivot, very smooth.
