Surplus stores used to have those folders for about $5 too. If only my crystal ball had been working back then! I am still hoping to get another of the USMC bolos (I don't have mine anymore), but refuse to pay $150 or so for one. A few years ago my wife got me a US 1917 bolo. It is almost as good a chopper as the USMC, and thanks to its shape can actually be used as a knife. A really big knife...
