First off, I am very sorry to hear about your health issues :-(
If you’re looking to get rid of a lot of things quick, but for less money, check out Arizona custom knives, they sell your knife (and give you like 2/3 of the value, I’m guessing) and you don’t have to worry about anything except getting a bank deposit when they sell.
Or, you could sell them on here, and get more money for them, but you’d have to post pics/threads in the WTB/WTS forums.
I’m sure ACK will want to see pictures also, and they may not be interested in certain things. Maybe your grandchildren will help you out with taking pics, etc…and you could cut them in on some profits…?
