I have been frequenting the local flea markets and garage sales, buying up a variety of hand tools. Pickaxes, mauls, shovels, rakes, hoes, saws, wood drills, yankee screwdivers, wedges, hammers, etc. I have also found sickels, brush cutters, even old rotary push mowers for relatively cheap. The other tools that I try to buy are old metal working tools, punches, chisels, measuring tools, and files. The best thing about the tools I'm buying is that while they are typically quite old, they are not considered antiques (without the high cost premium) and they really are better made than the ones you can buy today new. It's amazing what people will sell for a dollar or two. I just bring them home, sharpen them up if necessary, often not, and coat them with some precious oil and wrap them in newspaper. These items will be quite necessary in the upcoming years, and they don't attract attention now, people just think I'm a collector.
I will probably start putting them in caches around my property once I figure out a way to bury them without them getting all trashed, harder with files and cutting tools. I never really thought about hoarding ammo, .22 LR shells are cheap and probably easiest to store, and 12 Ga shells are pretty common and cheap. Guess it's time to start thinking about getting rid of/trading the oddball caliber guns.
22., .308, 12ga, and .38 will probably be in highest demand.
