While recovering from oral surgery today and getting an opportunity for some quality fondling time of my large and small 21, I noticed something. Maybe it's the drugs, but my small 21 born in summer of 2012 almost seems to have a slightly darker blade than my large born in December 2013. One might could call it slightly more aggressive stonewashing? I was curious to know if there's been certain points throughout the Sebenza lifespan that the blade tumbling process was changed which I'm sure it has, but when did you notice it?
