My two cents... Go to auctions and buy really old tools. They will be black and tarnished with age, but if you look real close, they are just as good now as they were 40 years ago. Take $100 of your money and buy a grinder and you can polish up this classics in no time. Take the rest of the money and put it in a 401K, or gold, or some other investment and forget about it for 40 years. When the time comes, you will be still have these tools, and over 100K....
