None of those have been carried (they arenāt safe queens or anything like that, I just have too many knives

). The darker 71 is from 2015, and while it may have darkened up a bit over time, it started out quite dark to begin with, much darker than any of those others. I donāt think the 86 could have changed much since it just came out last year, Iām fairly certain itās about the same color it was when I got it.
I can pretty much guarantee that any of them will darken up much quicker if you carry/use them. I donāt have any red linen micarta examples to show that, but here are a couple in natural canvas micarta comparing new (or close to new) and after some time and a bit of carry/use.
