This is kind of hard. Sure, I have thousands wrapped up in knives and a large firearms collection. My wife won't keep them all and I know my son has already laid claim to several and my daughter would be give the opportunity to choose a few out for herself.
For knives, I have a few that are valuable to "me". I think my son gets it as he's now in college and has an ROTC scholarship to hopefully graduate, get his commission and go Active Duty.
I've had my Mad Dog PATAK for years and it's been on the most deployments from South America to various deserts. I carried my Randall #15 in Iraq. Rick Hinderer along with his wife and In-Laws packed a massive gift box full of stuff (I shared with my troopers) when he shipped my X18 to Afghanistan.
I have my very first "high end" knife I ordered from Shomertec way back in the early 90's when I was a 2LT...I still have that Busse Steel Heart II (in A2 steel).
Everybody had Benchmade autos when I was at Bragg...I just had to get that Microtech DA/SOCOM that did a few jumps with me.
There are probably another dozen blades I've owned with stories and memories attached. I would only want to pass the blade on to keep those memories and stories alive and something for my kids to reminisce and often joke about (at my expense of course). As I'm sitting over here in Afghanistan (again), I've though pretty hard about this. All of my possessions are just objects, some of more value than others. If a few can be kept for those memories, than it will be worth it...the rest can be sold off as part of an estate sale and my family split the revenue after taking a nice vacation.
I allowed my son to sell a few of my knives, so at least I know he's experienced to find and assess values. Guns are a little more difficult and with my collection size, it would be easier to go with an estate sale. I have a spreadsheet that is pretty accurate with MSRP, current value including accessories (optics, rails, upgraded furniture, etc.). Heck I don't even want to think about the logistical nightmare it would be to put all the knives and guns up for sale; it would be exponentially worse for a grieving window and kids...
Stay sharp!
