People don't change, from the time an ancient practical mind figured out how a lever would throw a spear farther and how bending a limb and tying a gut on each end would throw a smaller spear even farther, men have progressed to space travel.
AH BUT..., development is NOT universal, even when all of the resources and abilities to invent or adopt a technology exist. :wink:
For example in Australia and in New Zealand, the bow and arrow were not used by the indigenous peoples. Now the Polynesians were sea faring, and did come into contact with cultures with bows, but they did not adopt the bow, nor develop them independent of contact. Cherokees made use of the blowgun..., so do South American paleo peoples today, but it didn't become a universal tool to the Eastern Woodland cultures, even with those that traded with the Cherokee, and knew of its use.
Steel skillets, cooking oil, charcoal, all were known to Europeans and those on the British Isles. YET..., stir-fry in a wok didn't develop, and even after contact was made by sea with China, the wok didn't spread into anglo society until after WWII. By your argument, since all of the needed ingredients and tech were known to be present, some white person must have used a wok in the 18th century, so then Moo Gu Gai Pan might be served at a North American historic home site as an "authentic" colonial dinner dish. :shocked2:
The debate isn't that whites "never" used neck knives, or that "only Indians used them"..., it's simply that we find no evidence of white, English speakers, using neck knives. SOME use this as the basis for their abstinence on neck knives, and SOME like me use the neck knife and admit it may not have been common, or might be wrong, and SOME don't care... :grin:
