Hi folks, I’ve got my Grail Knives List for 2021, and this year a BK9 tops it. I’m in the process of going through the vids and other reviews out there, and I’ve got kind of a dumb question. Has the Ka-Bar-produced model changed any since it was first introduced? Basically, if I read a review from 2014, is it still the same knife as one from 2020?
