Steven, Steven and Jim Cooper summed things up well from my experiences with Doug.
We lost a very good person who was passionate about pretty much all people and knives. He will be dearly missed by a lot of us.
In my case that says a lot, like many I never got the chance to meet him in person, yet I have thought about him and the way he treated people and his deep interest in knives this week. When I lose a friend like that, I try to incorporate the aspects that I admired most in some way in my life. He left some might big shoes to fill in a lot of ways. He left behind a big challenge for me.
