There cant really be a correct knife, as long as it was around during that time in question someone would have been using it.
Thats the thing with this challenge.. a lot of the kit we use nowdays, is the same as then with a few alterations, maybe a differnt materal.. the idea os to try to tempt people away from the modern kit and try something a bit differnt,
My way of thinking is there is a lot to be learnt from the old methods and materials, the challenge even brings up new or should I say old ways of thinking how we do things when camping.....I like doing things as close as I can without useing moden things, but thre is a cost so some time things have to be a bit moden...lol
I am not saying that it ok to turn up with Ti and a jet boil... thats not the idea... the idea lose that side of it...
