Otzi, the original forum member. carried one knife.
It was made out of a rock.
He either traded or traveled hundreds of miles to get the particular rock, but it was a rock.

Multiple knife carry is a first world issue: a response to a wild excess of resources rather than to necessity.

And, with some reservations, the cheapest knife available today is better than the best available 100 years ago. And the 100 year old knives appear to have been capable of all the cutting that was necessary.
