Already taken care of.
When I did my first bit downsizing of life stuff, I invited my family and friends over for a BBQ. I laid it all out on a table and everyone got to pick what they wanted. Kids, grandkids, nephews, nieces, co-workers/friends. The stuff nobody wanted like the big fixed blade Randall's and bladesmith society knives I sold off through A.G. Russell's. The wife and took a nice around the country trip with the money and had a ball.
I also did a lot of giveaways over in the traditional sub forum where I hung out a lot. Now I don't keep many knives on hand. Own just a few SAK's, a few different Opinels, and a Buck sheath knife that goes woods walking and fishing with me. I reached a point in life that the knives just didn't mean that much to me anymore. The people in my life are way more important than objects.
