My first GEC was a Northwoods Willamette Whittler in E. Ivory. I showed my son on his first weekend home from college; and told him, "I'm holding on to it for you, son." He then promptly made guacamole with it, so I brushed its teeth, and put it up. It will never get another patina, but it will be used from time to time. For me, I have a reminder of that specific time with my son. I totted it a few more times and then the Ivory Ban happened. Now it sits "safely." Yes that is a pun. ;^)
I didn't realize at the time how much sentiment would come from that knife, but I have no distortion as to what it does mean to me today.
