Since a young boy, I have loved the outdoors and the seemingly simplistic way it all works together.  Really when it is looked at closer there are billions of decisions in a cause and effect format acting on each other to make it as seamless as it may seem.  Knives were one of these decisions thousands of years ago.  Invented by man out of necessity, one decision - one instinct, for a tool needed to cope and thrive in their environment.
