I picked mine up new on the exchange over at B.F. a few months ago. 2019 version.
It's a very useful knife, I really like how thin it is, and the no finger choil is nice.
It's an inch or so longer than I usually go for, but it hasn't gotten in the way.
Seems like a 4" version would be popular (sorta like the 411, but thinner and a hair shorter).
I never see them getting talked about and they come up for sale pretty regular. I've already picked up a spare one (sage on sage) and if the right one came around with Brown Mudders, I probably would not be able to resist that one either.
