Thanks, GT. You’re too kind!
I took the screenshots from a YouTube version (higher resolution) of the same commercial. I’ll find the section of video with the knife, pause just before it, then use the spacebar (which will play/pause most video applications) to quickly play/pause, play/pause, play/pause until I get the shot I want. (Sometimes I miss it and have to go back.) Then I just take a screenshot (on Mac, Command+Shift+3 to capture the full screen, or Command+Shift+4 to snip a portion of the screen).
Other streaming video services (Netflix, Hulu) can be trickier because they have digital rights protections in place to prevent you from taking screenshots, but there are a few workarounds.
I think I just got lucky with the Vanguard.
My first thought when I saw the knife (probably because I’d been looking at them recently) was Randall Made Knives, many of which have that pronounced drop from the tang to the edge. Their Combat Companion model is probably the closest, but it’s definitely not a match, and given the price and waitlist, it wouldn’t make much sense, anyways.
Buck’s website was my next stop. I’ve browsed their fixed blade knives before, and I think I vaguely remembered that they made one with a short, broad drop point blade like that. I also think the Vanguard was (briefly) suggested as a possibility for the annual BF knife a couple years ago, so I would have seen it then.
