Nothing is written in stone. Obviously fire starting materials halfway up a Swiss mountain are more appropriate than fish hooks. Kits are ever evolving, hopefully improving and both versatile, yet with an eye to speciallization if we can pre plan. Commercial kits are governed by the bottom line, cost and profit. So the bottom is what you get.They also look at conventional offerings and become,well conventional. The danger is, falsehoods become repeated enough times to become the truth and the standard. Stamp 'survival knife' on another hollow handled sawback, boast of it's mythical 'stainless surgical steel' and sell it to somebody who saw Rambo kill a pig with one. I asked a local manufacturer "who are the experts you cite as assembling your kits?" Silence. "well, have you field tested the units?" More silence.<br><br>
