You mentioned a whetstone. Yup. That's a handy thing to have (and know how to use!) too. Never mind in a SHTF scenario. I saw a guy at the mall the other day who was sharpening kitchen knives at $1/inch. I save us a bundle, just with a $10 whetstone and a drop or two of 3-in-1.
Mrs WBill sometimes pokes me about putting a few things away (TP. I'm currently stockpiling lightbulbs, much to her amusement...) but everything that I have can either be used and replaced, or is just around the house for regular use, anyway.
Not too much gold at my place, though. And as for a "friggin arsenal", what I have is eminently useful and completely portable. I'm not planning to fight WW III from the top of my kid's treehouse.
Selling guns, gold and MRES will kill someone.
