Hi Ian,
I see where you're going now. Thanks for the clarification.
I think my answer, no joking, would be 'a brown one'. The number of types/styles/variations of knives that have been used over the centuries are legion, but the one thing that immediately makes a knife stand out as 'newfangled' is that it's in some horrible, bright, crayola colour. (the most horrid to my tastes being the rainbow coloured laminates- but some folks like em so more power to them).
'Traditional' (if I dare use the word after giving it such a hard time in my last post) knives tend to be brown. Wood, horn, antler, brown leather... brown. Occassionally black (very dark woods or black leather for dress knives and riverboat gamblers
) but usually brown.
Beyond that, I doubt you'd find a knife made today for which you couldn't find a 150yr old cousin (not a perfect copy, but you'd see the kinship between them).
Knives, like bows, are one of man's oldest tools and as such 'there's nothing new under the sun' (but I draw the line at dayglow lime plastic scales
)
