The now famous story of Ishi, 'the last Wild Indian' is worth reading. The Yano indians were once 3000 strong. Ishi's major subband, the Yani were massacred with only 30 survivors. 15 were killed shortly afterward by cattlemen.Then some prospectors came upon their camp and took everything for souveniers; firemaking, knives, bows, baskets-everything. They all died of starvation or exposure save Ishi, found near death in a ranch corral. There is a dangerous myth of the primal superhero 'McGuyver in breechcloth' who can whip up a fire, brush shelter and elk slowly turning on a spit for dinner by nightfall with only his obsidian equivenent to a SAK. First, you need the obsidian, and sometimes it just isn't there at your feet along with medicinal herbs. This is why minimalist 'bushcraft' knives with their trick looking firesteel slotted sheaths scare me. My kit? It's still a sickening mess of military surplus, state of the art commercial, home made coffee can stoves and raw materials gleaned from Nature. Early iron baldes were formed from meteorites. Now there is a real finite resource base!
